Abstract
Local density band structure and electron momentum densities have been calculated for Li and Na in ordered and disordered bcc structures usi ng the self-consistent LMTO method. Calculated Compton profiles are fo und to become more delocalized by the effects of disorder and electron -electron correlation. It is suggested that the reported discrepancies between calculated and measured Compton Profiles in Li are due to the rmal disorder. (C) 1998 Elsevier Science Ltd.
