Properties of Some Resonances of the 55Mn(p,g)56Fe Reaction in the Ep = 1.3 - 1.8 Mev Region

Abstract

Radiative decay of 21 resonances in the 55Mn(p,g)56Fe reaction was studied in the proton beam energy region Ep = 1.3 - 1.8 MeV. Branching of decay to many low lying bound states up to excitation energy Ex ~ 8 MeV was measured. Exact energy of all resonances has been established what pointed out that five of the resonances are very close doublets. For all studied resonances were determined their spin-parity charakteristics. Assignment of some resonances as isobaric analogues of the states in the 56Mn nucleus was discused and short note about energy systematics of isobaric analogue resonances was shown.
