Abstract
Discrete states in up to 25 MeV of excitation were studied by inelastic electron scattering. The measurements were performed at the Bates Linear Accelrator Center at 110° and 140°, and at momentum transfers ranging from about 1.2 to 2.5 . A number of the states discussed here have not been observed previously. Form-factor measuremetns are presented for eight candidates and for two candidates. The strongest state has T=2 and was observed at 22.40 MeV. Good T=2 candidates were found at 18.68 and 20.36 MeV, and good T=1 candidates were found at 8.52 and 12.99 MeV; the strongest candidate was found at 14.17 MeV. Form-factor measurements are also presented for several candidates. The M2 form factor for the lowest state at 5.53 MeV is similar in shape to that for the lowest state in , but is weaker in strength. Finally, form-factor measurements are presented for several high-lying normal-parity states, including strong excitations at 9.36, 9.71, 11.67, and 17.02 MeV.
