The average electron density in momentum space, viz. ( y ), where y(p) is the electron momentum density, is defined and shown to be experimentally measureable. The connection is obtained via the relation 8x'(y) =JB\*(s) d.r, where B(s) is the reciprocal form factor. The approximate relationships (p)
