Study of reactions /sup 45/Sc(n/sub e/, e'n)/sup 44m/Sc

The induced-activity method has been used to study the reaction /sup 45/Sc(n/sub e/, e'n)/sup 44m/Sc. The targets were bombarded by an electron beam at energies 165, 195, 225, and 260 MeV. The use of paired targets of scandium, separated by a converter of tantalum, permitted determination of the ratio of the cross sections for photo- and electrodisintegration of the nuclei. Comparison of the experimental data with theoretical calculations indicates a dominant role of E1 transitions and a small admixture of E2 transitions in the reactions studied.
