Abstract

Transition strengths 
2
w.u. M(E2) for gamma transition from first excited 21
+states
to the ground states that produced by pure electric quadrupole emission in even –
even nuclei of 58Ce and 60Nd have been calculated as a function of neutron number
(N). The life times for 21
+ excited states together with the intensities of γ0- transitions
measurements are used in calculations. The results thus obtained have shown that;
the nuclei with magic neutron number such as 58Ce140 and 60Nd142 have minimum
value for 
2
w.u. M(E2) . The reduced transition probabilities B(E2) are also
calculated and compared with the experimental data and other theoretical models.
