If the

**two**-**body**force i>(l, 2) is singular, as actual nuclear forces seem to be, thesimple H-F wave function becomes a poor approximation; as an illustration of this

, consider the second-order ground-state energy shift (3.1) AE = - i f T l(*r|^/»)]!

3'2. The canonical transformation (*). - In the independent pair approximation, it is

assumed that close encounters of three particles (or more than ... The

transformations S (3.2) will therefore be of the type Q being a hermitian

kernel.
