摘要：
Rotational bands have been found in Co-57 using the Si-28(S-32, 3p) reaction at 130 MeV. The bands, extending the mass 60 region of large deformation down to Z = 27, are signature-partner sequences. Their quadrupole moments are similar to those of bands in the neighboring nuclei. The features of the new bands are described by Skyrme Hartree-Fock calculations favoring a configuration assignment with one neutron and one proton excited in the respective 1g(9/2) intruder orbital. An attempt to describe the magnetic (M1) properties of the signature-partner structure is also presented.
