Fragments of the 1[ital g][sub 9/2] isobaric analog resonance in [sup 53]Mn corresponding to the 3.715 MeV state ([ital S][sub [ital n]]=0.57) in [sup 53]Cr were located using the [sup 52]Cr([ital p],[ital p][sub 0]), [sup 52]Cr([ital p],[ital p][sub 1]), [sup 52]Cr([ital p],[ital p][sub 1][gamma]), [sup 52]Cr([ital p],[ital p][sub 2][gamma]), and [sup 52]Cr([ital p],[gamma])[sup 53]Mn reactions. Differential cross sections were measured in the 4.06--4.28 MeV, and the [gamma]-excitation curves in the 4.04--4.35 MeV proton energy region. Spins, parities, and partial widths were determined with the aid of [ital R]-matrix analysis for all resonances observed in the region. The spins of the 1[ital g][sub 9/2] resonance fragments were found independently from ([ital p],[ital p][sub 1][gamma]), ([ital p],[ital p][sub 2][gamma]), and ([ital p],[gamma]) angular distribution measurements and their analyses. Nineteen fragments were identified and their [gamma]-branching ratios to low lying levels of [sup 53]Mn were also deduced. Partial widths for each fragment in all four channels were derived. Channel-channel correlations were calculated. Fine structure analyses were carried out in all open channels. Inelastic spectroscopic factors and Coulomb displacement energy for the 1[ital g][sub 9/2] state were also derived.
