Unexpected honour
Dear Respected Sir, Have I done anything wrong! I am really scared, because I am not that much sound in english. I wrote like that because I respect Prof. Armel very much.

Re: Unexpected honour
Dear Dr Apu, Don't worry. You have done nothing wrong. It is just a private Anglo-French joke, and it is not (yet) forbidden to make jokes :-) I am sure Armel will be delighted - he has been called worse things :-) Alan.

Seriously Thanks guys I did not know about this site till I retired and have wished I knew a lot earlier. Try also the dissident SDPD Mailing List : http://groups.yahoo.com/group/sdpd/ (though Sir Kenneth is also a subscriber...). Armel
Job vacancies at ISIS
ISIS is a world leading facility for condensed matter research using neutron scattering and muon spectroscopy, with a strong scientific user programme and extensive international links. ISIS is in a period of major expansion, including the construction of a second Target Station, with an initial phase of 7 new instruments, to be operational in 2008. We are looking for world-class scientists, instrument developers and electrical engineers who can make major contributions to our current and future research programmes. Senior Scientists (2 positions) Scientists (8 positions) Electrical Engineers (9 positions) PA to the Director (1 position) Information about ISIS can be found at http://www.isis.rl.ac.uk. Complete details and application forms can be found at http://www.cclrc.ac.uk/Activity/Jobs VN2624: Senior Scientist (Diffraction) Type Full-time Department/Centre ISIS Department Location RAL Office RAL All application forms must be returned by 6 December 2004. Description We are looking for a scientist with a proven research record to play a leadership role in the development of diffraction techniques at ISIS, both in terms of instrumentation and applications. The post will involve line management, project management and budget management responsibilities. The jobholder should be able to lead a team to achieve both short term and long term goals. The successful candidate should demonstrate a broad experience and outlook and an innovative approach. VN2625: Senior Scientist (Biomolecular Sciences) Type Full-time Department/Centre ISIS Department Location RAL Office RAL All application forms must be returned by 6 December 2004. Description The Large Scale Structures Group provides neutron scattering facilities and expertise for the study of surface and interfacial phenomena across a diverse range of research areas such as polymers, colloids, biological systems and magnetic thin films. The Group currently supports 3 neutron instruments (reflectometry and small angle neutron scattering) and is designing 4 instruments for the second Target Station Project. A full time vacancy exists to support and develop the study of biological systems at ISIS by fully exploiting the unique capabilities of small angle scattering, reflectometry and deuteration. Biomolecular sciences have been highlighted as a central scientific theme of the second Target Station project, and as such the position represents an excellent opportunity to expand collaborative and personal scientific research programmes in this key expanding area. It is anticipated that the successful applicant will work extensively with the existing neutron community and provide expert support for their activities at ISIS. Furthermore, they will proactively engage with potential new user groups and interact with the biomolecular sciences activity on the Rutherford campus, in particular that related to the new Diamond synchrotron and the associated research complex, by leading initiatives to exploit the use of neutron scattering in biological science. The position requires a proven research record in biomolecular sciences. Relevant neutron scattering experience is desirable, though not essential. Complete details and application forms can be found at the central CCLRC Job Vacancy Pages VN2623: Instrument Scientist, Molecular Science Group (Inelastic/quasi-elastic scattering) Type Full-time Department/Centre ISIS Department Location RAL Office RAL All application forms must be returned by 6 December 2004. Description There is an opportunity for a highly motivated and independent scientist to assume responsibility for the scientific programme and future development of the two backscattering instruments, IRIS and OSIRIS. The jobholder will be required to provide scientific support for the ISIS User Programme and will be strongly encouraged to build collaborations with UK and foreign visiting scientists. Applicants should have a PhD in a relevant science area. The successful candidate will have a proven track record in molecular science. Experience with inelastic and/or quasi-elastic neutron scattering is an advantage. The ability to carry out independent research and an innovative outlook towards instruments and technique development will be counted as strong assets. Experience in the use of central facilities and the proven ability to develop instrumentation and/or data analysis software would also be an advantage.

Description We are looking for two highly motivated and independent scientists, who will assume responsibility for a world-leading scientific, instrument design and instrument-operation programme within the ISIS crystallography group. The jobholders will be required to provide an appropriate level of support for the ISIS User Programme
rietveld refinement
I am a new user of rietveld softwares. Can anyone suggest me any program or software based on reitveld algorithm and giving the following results... 1) size distribution of particles in a sample. yours sincerely venkat
RE: rietveld refinement
Hi Venkat, If you mean to use rietveld on X-ray data I don't think you can get particle size distributions. X=ray data will give you an average crystallite size but this is not a distribution just an average. Also, it is crystallite size and the actual particles size can be different if the crystallites are agglomerated. Have you considered trying dynamic light scattering? Cheers, Chris will I am a new user of rietveld softwares.

Re: rietveld refinement
This is where the real fun starts (if you're a masochist!). I just finished doing some work along those lines this afternoon, and managed to get it to work(ish) eventually. The double-Voigt analysis can give you Dv (volume weighted domain size) and Ds (surface weighted domain size). If you assume a log-normal size distribution (not completely unreasonable) it is possible to work backwards and derive the distribution from these values. However, you need really good data or you get complete rubbish because of the correlations. Davor Balzar covers some of this in his recent J.Appl.Cryst. paper (page 911 latest issue) and Popa and Balzar, J.Appl.Cryst. v35 (2002) 338-346. It gave me a bit of a brain-ache but it does work!

Lobanov [mailto:[EMAIL PROTECTED] Sent: November 18, 2004 1:51 PM To: [EMAIL PROTECTED] What I remember is that Breadth outputs the distributions. What might be the solution is to convert (write a program) Rietveld peak output to Breadth input. However, I have never done this myself; I converted Xfit-style peak files only, which is pretty straightforward. It is a separate question to what extent those distributions are physical...
