The variation of the

The variation of the

**ground**-state wave function is then written as (4.2) <P'o=exv[iF]0o. In order to demonstrate again the nature of the increment Q eq. (2.17) in

energy, let us assume thay we apply the variation exp [ iF] to the exact

**ground**state ...

**ground**state ought to be equal to each other and equal to the rate inneighbouring even A nuclei, since only the parent can contribute to the

Comparing (53) with (12.4), we see that the inclusion of
