On lf2p nuclei. Gamma ray spectroscopy on states in ESZn and 6 7 Z n using 62t64Ni(x,n) reactions.

On lf2p nuclei. Seniority-three states of the V ( ~P ~; ~, 1 f512, 2 ~~1 ~) ~ configuration in 69Ni.

The structures of 55Mn, 55Fe and 57Fe have been investigated by coincidence, yield, angular distribution, and linear polarization measurements of gamma-ray decay from alpha-induced reactions on 52Cr and 54Cr at Eα = 14.2 MeV. Several high-spin states are assigned: In 55Mn 984 keV 9/2-, 1 291 keV 11/2- (both confirmed) and 2 309 keV 13/2-; in 55Fe 931 keV 5/2-, 1 316 keV 7/2-, 1 408 keV 7/2-, 2 211 keV 9/2- 2 300 keV 9/2-, 2 539 keV 11/2- (all six confirmed) and 2 814 keV 13/2(-), 2 982 keV 11/2(-), 3 071 keV 11/2-, 3 419 keV 15/2(-) and 3 456 keV (tentative 13/2-); in 57Fe 316 keV 3/2-, 706 keV 5/2- (both confirmed) and 1 007 keV 7/2-, 1 197 keV 9/2-, 1 357 keV 3/2(-), 1 989 keV 9/2(-), 2 355 keV 11/2-, 2 455 keV 9/2-, 2 879 keV 13/2-, 3 135 keV 15/2(-), 3 268 keV 13/2(-) and 4 429 keV, 4 524 keV (spins undetermined).

The reactions S4Sr(e, n)STZr and s~'Sr(e, 3 n)87Zr were used to populate excited states in STZr. The de-excitation of these states was studied by in-beam 7-ray spectroscopy. A number of new high-spin states were observed. Lifetime measurements were also performed. The results are discussed within the frame-works of the shell model and the particle-core coupling model.
