摘要: The near-yrast structure of the weakly deformed, ‘‘transitional,’’ nucleus 101 Ru has been investigated using fusion-evaporation reaction 96 Zr( 9 Be,4n) at a beam energy approximately 44 MeV. experimental data are compared with theoretical calculations cranked Woods-Saxon-Strutinsky method. yrast positive-parity structures observed to undergo backbend, consistent crossing an aligned (nh11/2) 2 configuration. h11/2(@550# 1 ) intruder band configuration is extended tentative spin/parity ( 47 and excitation more than This exhibits properties which can be explained by rotational alignment pair midshell g9/2 protons, in contrast behavior heavier N557, odd-A isotones where predicted proton delayed favor neutron alignments. effect static g deformation on theoretically means shell model. crossings found significant triaxial rigidity, persistent into medium-spin regime.
