摘要：

Observation of gamma-gamma coincidences from the reaction 124Sn(Mg-24,xn) at 145 MeV has revealed a discrete superdeformed rotational band and evidence of a superdeformed continuum in 142Sm. This result is consistent with cranked shell model calculations indicating shell gaps favorable to superdeformed structures in N = 80, Z approximately 64 nuclei. It is proposed that the 142Sm band may be described by a proton hole in an 143Eu core. The dynamic moment of inertia of the superdeformed band is more constant than predicted by the model. This may be due to a strong residual interaction between a 6(1) proton intruder and aligning N = 6 valence neutrons.
