Superdeformed band in [sup 142]Sm
Observation of [gamma]-[gamma] coincidences from the reaction [sup 124]Sn([sup 24]Mg,[ital xn]) at 145 MeV has revealed a discrete superdeformed rotational band and evidence of a superdeformed continuum in [sup 142]Sm. This result is consistent with cranked shell model calculations indicating shell...

| description | Observation of [gamma]-[gamma] coincidences from the reaction [sup 124]Sn([sup 24]Mg,[ital xn]) at 145 MeV has revealed a discrete superdeformed rotational band and evidence of a superdeformed continuum in [sup 142]Sm. This result is consistent with cranked shell model calculations indicating shell gaps favorable to superdeformed structures in [ital N]=80, [ital Z][similar to]64 nuclei. It is proposed that the [sup 142]Sm band may be described by a proton hole in an [sup 143]Eu 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[sub 1] proton intruder and aligning [ital N]=6 valence neutrons. |
