High-spin states in the odd-odd N=Z nucleus Mn-50 have been identified. At low spin, the T=1 isobaric analogue states of Cr-50 are established up to I-pi=4(+). At high spin, the T=0 band built on the low-lying I-pi=5(+) isomer in Mn-50 becomes energetically favored and this band is observed up to its f(7/2)-shell termination at I-pi=15(+). Spherical shell model calculations in the full pf shell are found to be in excellent agreement with the experimental results. In addition, a weak side band in Mn-50 is observed to spin (12(-)) and is interpreted as a possible octupole vibrational structure. [S0556-2813(98)50211-7].

Abstract
High-spin states in the odd-odd N=Z nucleus Mn-50 have been identified. At low spin, the T=1 isobaric analogue states of Cr-50 are established up to I-pi=4(+). At high spin, the T=0 band built on the low-lying I-pi=5(+) isomer in Mn-50 becomes energetically favored and this band is observed up to its f(7/2)-shell termination at I-pi=15(+). Spherical shell model calculations in the full pf shell are found to be in excellent agreement with the experimental results. In addition, a weak side band in Mn-50 is observed to spin (12(-)) and is interpreted as a possible octupole vibrational structure. [S0556-2813(98)50211-7].File in questo prodotto:
