I am troubled by the first line in section II. "In the low-energy range (kR ?á 1, where R is the radius of a nucleon) and for |r| . R the long wavelength approximation |'(r)| = |'(0)| = fjk(k)/?ãV (6)" (Poor reproduction in ASCII text - please see original to make sense of this). If R is the radius of a nucleon, then it is something less than 1 fm. If the approximation in (6) is only valid when |r| < R, then is it only valid for distances less than 1 fm. However at these distances, the nuclear force reigns supreme, and nuclear reactions happen near instantaneously anyway. IOW by the time the approximation takes effect, it is useless. Besides, how does one get that close in the first place? > >ABSTRACT >Nuclear processes in solid environment are investigated.
