Abstract

A rotational band based on the proton h11/2 orbital has been observed to high spin (79/2Latin small letter h with stroke) and high rotational frequency (Latin small letter h with stroke1.0 meV) in the nucleus Sb51113. The measured transition quadrupole moment is Q0=4.40.6 e b, consistent with an axial prolate deformation of 20.32. A large interaction strength (36060 keV) has been measured for the rotational alignment of h11/2 neutrons which, together with a considerable delay in the crossing frequency (Latin small letter h with stroke0.09 MeV), is construed as the first direct evidence of a large high-j proton-neutron interaction.
