Abstract

A new method, the operator expansion method, is derived and discussed.Using this method, the ..beta beta.. decay of /sup 48/Ca isrecalculated. It is shown that by employing the Paris forces our method yieldsa matrix element suppressed by a factor of about 2--6 for the2..nu beta beta.. mode, while for the 0..nu beta beta.. mode our calculationconfirms the results obtained with the conventional closure approximation.
