The branching ratios for leaving the CO + ion in a particular vibrational level of the ground X 2 Ʃ + state have been determined as functions of photon energy through the n = 3 autoionizing Rydberg state converging to the B 2 Ʃ + state of CO + ; there are substantial differences between theoretical and experimental Franck-Condon factors when ‘on’ resonance. The branching ratios have been converted into absolute partial cross sections by normalizing to existing data obtained by using line sources. The asymmetry parameter β has also been determined for each vibrational level in this spectral range. Considerable variations in both have been observed in the region of this resonance.

Octupole Excitation

Elastic and inelastic scattering of protons on 7Li, 9Be, and 12C have been studied, using the 100-MeV proton beam from the McGill synchrocyclotron. Differential cross sections for the various groups of scattered protons were measured over an angular range of 5° to 90° (lab). For proton groups resulting from a quadrupole excitation in the target nucleus, the angular distribution was found to increase at scattering angles less than 10°. Angular distributions corresponding to an octupole excitation were observed to decrease at small angles. The results have been compared with existing data in this energy region.
