Abstract

Excitation energies and nuclear lifetimes of levels in Co55 have been measured via the reactions Fe54(He3, dγ)Co55 induced by 11.0 MeV incident He++3 particles. The Doppler shifted γ-ray spectra, taken in coincidence with the outgoing deuterons, were fitted by a line shape analysis program to determine the lifetimes. Experimental results for excitation energies (±1 keV) and lifetimes (ps) are: 2166, 0.141-0.021+0.020; 2566, 0.620-0.090+0.120; 2940, 0.590; 3324, 0.090-0.012+0.017; 4166, 0.050-0.005+0.010. NUCLEAR STRUCTURE Fe54(He3, dγ), E=11 MeV; measured Eγ, Doppler shifts; Co55 deduced levels, lifetimes.
