Abstract

The level scheme of56Fe was built up from γ-γ coincidence measurements using Ge(Li) detectors and a Dual Parameter data collection system. The previously suggested γ-transitions [8] of 263.3, 410.9, 485.2, 674.7 and 1,462.3 keV were confirmed and evidence found for a new 655.0 keV γ-transition between the levels at 4,100.32 and 3,445.32 keV. No evidence was found for the transition of 2,657.4 keV and the previously proposed β+-feeding of the level at 3,600.3 keV is ruled out, while the existence of a level at 4,447.5 keV is suggested. The relative intensities and branching ratios of 44 transitions were determined. A calculation of experimentalK-shell internal conversion coefficients α(K) showed large discrepancies from previous studies for the 3,009.6 and 3,451.2 keV transitions, the latter being assigned a different multipolarity. Logft values were calculated and spins and parities of the levels deduced. In particular the assignment of 3+ is verified for the level at 4,297.97 keV.
