โœฆ Synopsis

The 180(p,p) IsO and '*O(p, IX) 15N excitation functions were investigated in the energy range E, = 1.39 to 3.20 MeV by simultaneous observation of protons and w particles at 135". Only twelve prominent elastic scattering levels were observed at this angle and at 45", despite the high experimental resolution (less than 400eV energy spread). Only one resonance was observed for the proton interaction with I60 under the same conditions. R-matrix expressions for multichannel multilevel cross sections were programmed and used to analyze these data. Three of the resonances were determined to be s-wave and seven d-wave, while only two were found to have odd parity. Spins were assigned to each of these twelve resonances except for one d-wave.

The experimental energies and widths of the resonances in rgF are compared with those of a shell-model calculation. This model predicts positive parity 2plh states that are formed by treating the target '\*O as the core. It is assumed that these doorway states fragment via couplings with more comple
