Superdeformed band in asymmetric N > Z nucleus, 40Ar and high-spin states in A = 30 ～ 40 nuclei (Conference Paper)

摘要

A rotational band with five cascade γ-ray transitions was newly found in 40Ar. The deduced transition quadrupole moment of 1.45+0.49 0.31 eb has demonstrated this band as having a superdeformed shape of β2 ~ 0.5. The structure of the band was discussed in the framework of cranked Hartree-Fock-Bogoliubov calculations and the assignment of multiparticlemultihole configuration has been made.
