Investigation into the B ( E 2) anomaly in 144 Nd using Coulomb excitation
The ratio of B(E2) strengths between the lowest lying members of the ground state band in Nd144, B4/2=B(E2;41+?21+)/B(E2;21+?01+), which is used to quantify collectivity in nonmagic nuclei, has been remeasured by means of Coulomb excitation. Ambiguities in literature values for this ratio have been resolved. The results are discussed in terms of the interplay of collective and single-particle degrees of freedom, and in the context of the formation of collective structures in the A=140 mass...[Show more]
