摘要：
High-spin states of Rh-99 were studied through in-beam gamma-ray spectroscopy by using the reaction Zn-68(Cl-37, alpha 2n). The upper part of the band based on the g(9/2) proton orbital was rearranged in four parallel cascades. Negative parity was tentatively assigned for the side-band that previously had no parity assignment. This negative-parity band was interpreted as having the configuration of pi(g(9/2))(5)nu[(d(5/2)g(7/2))(3)(h(11/2))] and extended up to 51((-))/2, which is possibly a terminating state. The band based on the p(1/2) proton orbital was observed up to 29(-)/2 and its property was compared with those of neighboring odd-Z nuclei from the two different viewpoints, one of which is a weakly deformed soft rotor with spin alignments and the other is vibrational to rotational evolution along the band.
