Özet:

 

In the Random Phase Approximation (RPA), using the analyticproperties of the nucleus transition matrix elements and by means of contourintegrals and residue theorem, we obtained an analytic formula for the Energy Weighted Sum Rule (EWSR) of the M1 transitions as a function of thedeformation parameters of the excited states of the nucleus. It is shown thatan essential decrease of the experimental M1 transitions rates may be due tothe change of nuclear shape caused by the transitions between diﬀerent energy levels. The latter may be also responsible for the observed quenching ofthe M1 sum rules. The numerical calculations are carried out, and the deformed dependence of the sum rules for the140Ce,154Sm,156Gd and196Pt isanalyzed.
