-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Paul,
thank you for the answer. I was curious, especially since there was a recent paper on anomalous phasing with neutron scattering (doi:10.1038/srep31487), and wondered if this was related. I also appreciate seeing development in neutron crystallography.
