Isovector pairing in odd-odd N=Z {sup 50}Mn

High-spin states in the odd-odd N=Z nucleus {sup 50}{sub 25}Mn have been investigated. A sequence of states up to J{sup {pi}}=6{sup +} has been assigned as the T=1 analogue of the yrast band in {sup 50}{sub 24}Cr for the first time.

description High-spin states in the odd-odd N=Z nucleus {sup 50}{sub 25}Mn have been investigated. A sequence of states up to J{sup {pi}}=6{sup +} has been assigned as the T=1 analogue of the yrast band in {sup 50}{sub 24}Cr for the first time. The differences in energy between levels in these bands are interpreted in terms of rotational alignments and the effect they have on the Coulomb energy of the nucleus. Comparisons with shell model calculations show that the Coulomb energy difference between the T=1 analogue structures is an important indicator of the competition between isovector pairing modes in N=Z nuclei and their isobars.
