Abstract

The elastic scattering of $α$ particles by ${}^{9}{Be}$ has been studied in the bombarding energy range of 1.7-6.2 MeV. 10 excitation functions in 50-keV steps and five angular distributions near 5 MeV were measured. The elastic scattering data in the 3.5-5.0-MeV region were analyzed with the compound-nucleus theory using a computer code which evaluates the cross section in the "single-level" approximation. Analysis in terms of seven resonances reproduces many of the features of the data. Tentative spin and parity assignments are given.
