Electroexcitation of Be9 levels in the 14-18-MeV region

The form factors for electroexcitation of the lowest T=32 levels in Be9 (14.39 MeV, 32-; 16.97 MeV, 1/2-) have been measured for momentum transfers between 0.5 and 1.1 fm-1. Results are also presented for levels of unknown TJπ at 16.63 and 17.48 MeV excitation. Radiative widths have been extracted. The form factor of the 16.63-MeV state is compared with simple-spherical and deformed shell-model form factors. The ground-state rms radius and quadrupole moment have been deduced from the elastic scattering data. © 1973 The American Physical Society.
