Abstract
Using the facilities of the Darmstadt electron linear accelerator the cross sections for the excitation of the 4.46 and 5.04 MeV level in B11 were measured at various angles between 104 and 1650. The following radiation widths to the ground state (in eV) have been deduced: 0.60±0.09 (Ml)+0.016±0.002 (E2) for the 4.46 MeV level and 1.73±0.14 (M1) for the 5.04 MeV level. Transition radii were evaluated for these levels.
