Properties of some resonances of the Mn-55(p,gamma)Fe-56 reaction in the E-p = (1.3-1.8) MeV region

Radiative decay of 21 resonances in the Mn-55(p, gamma)Fe-56 reaction was s tudied in the proton beam energy region E-p = (1.3-1.8) MeV. Branching of d ecay to many low lying bound states up to excitation energy E-x approximate to 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 their spin-parity characteristics were determined. Assignment of some resonances as isobaric analogues of the states in the Mn -56 nucleus was discussed and short note about energy systematics of isobar ic analogue resonances was given.
