INELASTIC ELECTRON-SCATTERING FROM B-10

Electron scattering form factors were measured for six transitions in 10B in the momentum transfer range 0.61 to 1.81 fm-1. Ground state radiative widths were extracted by means of the generalized Helm model for the levels at 1.74 MeV (M3), 5.17 MeV (M1 + M3), 6.03 MeV (C2 + C4), 7.48 MeV (M1), 8.07 MeV (C2) and 8.9 MeV (M1 + M3 or M2). The transverse form factors for the 1.74 and 5.17 MeV levels agree well with predictions based on Cohen-Kurath wave functions. The longitudinal form factor for the 6.03 MeV state shows effects due to the deformation of 10B and is in good agreement with the deformed Hartree-Fock shell model prediction of Bouten and Bouten. Estimates are presented for the ratios of radiative pion capture rates leading to analogue states in 10Be. © 1979.
