Abstract
Eighteen previously unknown gamma -ray transitions were identified in the T -z = -1/2 nucleus Fe-51 following the fusion-evaporation reaction S-32(Si-2 8,2 alpha 1n)Fe-51. The lever scheme reaches the fully aligned I-pi = 27/2( -) terminating state of the five holes in the f(7/2) shell. The 17/2(-) sta te was found to be isomeric, and the lifetime was measured to be 2.87 ns. T he mirror symmetry of Fe-51 and Mn-51 is discussed, and the level scheme of Fe-51 is compared to shell-model calculations.
