Abstract
Excited states in have been observed by measuring the differential elastic scattering cross section of for proton energies from 2.0 to 5.0 Mev and the differential inelastic scattering cross section of ( Mev) for proton energies from 3.0 to 5.2 Mev. Resonances were observed at 2.080, 2.88, 3.095, 3.334, 3.571, 3.710, 3.98, 4.235, 4.36, 4.43, and 4.884 Mev, corresponding to excited states in at 4.732, 5.50, 5.711, 5.942, 6.171, 6.305, 6.57, 6.812, 6.93, 7.00, and 7.438 Mev, respectively. Single-level dispersion theory analysis indicates assignments , respectively, for these states.
