Systematics of magnetic dipole transitions

Abstract

An empirical approach to distinguish between l-allowed and l-forbidden magnetic dipole transitions is made. The reduced lifetimes of these transitions are calculated and their variation with neutron number is studied. It is observed that their general tendency is to remain constant while l-forbidden and l-allowed odd-proton magnetic dipole transitions are distinguishable from their reduced lifetimes, it is not so in the case of odd-neutron transitions. A slight increase in reduced lifetime with neutron number is observed for fixed proton number.
