In addition to the known (f/sub 7/2/)/sup n/ multiplets, states with spins ranging up to 10/sup +/ (11/sup +/) have been identified in /sup 5/0Ti, /sup 5/2Cr, and /sup 5/4Fe via (..cap alpha..,2n..gamma..) reactions. Shell-model calculations including excitations of one particle from the N = 28 core successfully account for the newly observed states and indicate their 2p/sub 3/2/ neutron character in /sup 5/0Ti and /sup 5/2Cr. The experimental results also require configuration mixing of about 20% for the low-lying f/sub 7/2/ states.
