Lifetimes of the First and Second Excited 3/2 exp - States in exp 41 Ca Using the exp 2 H( exp 40 Ca,p) exp 41 Ca Reaction

摘要

A high-velocity shift attenuation experiment was performed using an inverse reaction with a exp 40 Ca ion beam on a deuteron target. The mean lives of the two first 3/2 exp - levels at 1943 and 2462 keV have been determined as 0.79+-0.10 and 6.7+-0.8 psec respectively. Concurrently the lifetime of the 2670 keV level was found to be 4.5+-1.3 psec. An empirical electric quadrupole charge is extracted for the neutron from the 1943(3/2 exp - ) implies g.s.(7/2 exp - ) gamma -ray transition probability using a shell model wave function in the fp space.
