Gamma ray spectra from the reaction Mn 55 ( p , y ) Fe 56ß have been measured at the isobaric‐analogue resonances at E p = 1769 ± 4 keV and 1806 ± 4 keV respectively with a 15 cm 3 Ge(Li) dedector. Double correlation for the transition from the resonance level to the second excited state of Fe 56 has been measured for the two cases. Proton elastic scattering was also studied at each resonance at the angle 150°. Analysis of the ( p , y ) and ( p , p ) works yields a J π assignment 4 + or 5 + and 3 + for the two mentioned resonance states, respectively, which are the isobaric‐analogues of the 0.454 MeV and 0.486 MeV states of Mn 56 . The proton partial width and the total width for each resonance state were also determined.
