Abstract
Measurements of the cross sections for the reactions , , , , , and have been made for incident particle energies of 2 to 4 MeV. Preliminary Legendre-polynomial analyses of measured angular distributions were used to guide a multilevel multichannel -matrix analysis. In the -matrix formulation a set of level parameters for eight resonances has been found which can account for the observed cross sections in all of the channels. The level at MeV in has been identified as the isobaric analog of the second excited state in . The reduced widths of this level in the various channels indicate that it contains at least a 10% admixture of . A series of strong -particle levels has been found which fit into the -particle core-excited threshold-state model scheme for .
