Abstract

The differential cross section and polarization for neutrons scattered from 10B have been measured at En = 2.63 MeV (Ex = 13.85 MeV). The results of this experiment and other available neutron scattering data in the range 1 < En < 4 MeV are interpreted through a single-level R-matrix calculation over the region 12 < Ex < 15 MeV. Based on this analysis the most probable Jπ assignment for the 14.0 MeV level in 11B is 112+. The anomaly near Ex = 13.1 MeV can only be explained in terms of two overlapping levels having assignments of (52, 72) and (32, 52, 72)+.
