Abstract

Excitation functions for proton elastic scattering on Mn^55^ at proton energies from 1320 KeV to 1480 KeV have been measured at the angles 135° and 150°. Anomalies in the differential elastic scattering were observed at E~p~ = 1350 ± 4 KeV, 1385 ± 4 KeV and 1445 ± 4 KeV respectively. These resonance states are the isobaric analogues of the ground, first excited and second excited states in Mn^56^ respectively. Analysis of the results showed that these resonance states are best fitted to a J^π^ = 3^+^, 2^+^ and 1^+^ which is in excellent agreement with the J^π^ values of the corresponding states in Mn^56^. The total widths and proton widths of these states were determined.
