Abstract
The momentum distribution and possibility of Bose-Einstein condensation in a Bose solid is discussed. It is shown that for a wide class of wave functions describing solids of general symmetries, Bose-Einstein condensation does not exist, provided the sum of certain normalized overlap intergrals is less than 1. The realistic parameters of solid He4 are such that the above condition is obeyed.
