摘要: A rotational band based on the proton [ital h][sub 11/2] orbital has been observed to high spin (79/2[h bar]) and frequency ([h bar][omega][congruent]1.0 meV) in nucleus [sub 51][sup 113]Sb. The measured transition quadrupole moment is Q][sub 0]=4.4[plus minus]0.6 e] b, consistent with an axial prolate deformation of [beta][sub 2][congruent]0.32. large interaction strength (360[plus minus]60 keV) for alignment neutrons which, together a considerable delay crossing ([Delta][h bar][omega][congruent]0.09 MeV), construed as first direct evidence high-[ital j] proton-neutron interaction.
