Abstract

The inelastic scattering of 21.5-Mev alpha particles by nitrogen has been investigated. Previously unreported levels at 7.94±0.07, 8.45±0.07, and 10.05±0.07 Mev in $N^{14}$ are observed. Levels at 2.31, 7.4, 7.7, 8.06, and 9.49 Mev reported in other reactions are not observed. This confirms the isotopic spin $T = 1$ assignment to the 2.31- and 8.06-Mev levels, and suggests such an assignment for the 9.49-Mev level. The status of the 7.4- and 7.7-Mev levels is uncertain.
