N14(α,d)O16Reaction at 40 MeV

Abstract

The ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}(\alpha ,d){}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ reaction has been investigated up to an excitation energy of 20 MeV using a 40-MeV $\alpha$-particle beam from the Berkeley 88-in. cyclotron. Angular distributions were obtained for the three strongest levels at 14.40 ± 0.03, 14.82 ± 0.03, and 16.24 ± 0.04 MeV. Widths for these states, with the experimental resolution subtracted in quadrature, are 30 ± 30, 69 ± 30, and 125 ± 50 keV, respectively. Evidence for the probable [${}_{}{}^{14}{}_{}{}^{}\mathrm{N}\left(1^{+}\right)+\left(d_{\frac{5}{2}}\right)_{}^2{}_{5^{+}}{}^{}$] configuration of the three states is discussed.
