• The approximation method using projection operators, which was previously proposed and applied to calculations of hindered beta matrix elements, is reexamined from a more general viewpoint and extended to a method suitable to include both backward and forward correlations. The present method is compared with the previous methods, especially the RPA in the pairing model. New formulae are applicable not only to the hindered matrix elements but also to unhindered matrix elements. The merit of the present method is that the coherent effect of small admixtures in wave functions is expressed as sum rules, which can also be regarded as semi-phenomenological parameters, and the way to estimate neglected terms is clearly seen because the method is based on identities.
