Lifetime measurements of excited states in ⁵⁷Mn

NUCLEAR REACTIONS ⁵⁵Mn(¹⁸O, ¹⁶O)⁵⁷Mn, E=38 MeV; measured Eγ, Iγ, γ(θ), particleγ-coin. ⁵⁷Mn; deduced T_1/2 of the first 9/2^- and 11/2^- excited states, B(M1), B(E2). ^{51,53,55,57,59,61}Mn; calculated B(M1), B(E2). ^{47,49,51,53,55,57}Sc, ^{49,51,53,55,57,59}V, ^{53,55,57,59,61,63}Co; calculated B(E2). Experimental values for T_1/2 obtained with Doppler-shift attenuation method. Shell-model calculations with GXPF1A and KB3G interactions. Setup of 11 HPGe detectors positioned in 2 rings and combined with six solar-cell particle detectors at FN tandem accelerator (Institute for Nuclear Physics, University of Cologne).
