N15(d, p)N16 Reaction and the Low Excited States of N16

Abstract

The angular distributions of proton groups to the first three excited states of ${\mathrm{N}}^{16}$, produced in the reaction ${\mathrm{N}}^{15}(d, p){\mathrm{N}}^{16}$, have been measured at $E_d=2.75\mathrm{}$ Mev in the laboratory system. These distributions show strong resemblance to the predictions of stripping theory and have been compared to curves calculated from the formula for the differential cross section given by Bhatia et al. The most reasonable values of $l_n$ in the reactions leading to the states at 0.113, 0.300, and 0.391 Mev are $l_n=0, 2, \mathrm{and} 0$, respectively, indicating spin and parity assignments $0^{-}$ or $1^{-}$; $1^{-}$, $2^{-}$, or $3^{-}$; and $0^{-}$ or $1^{-}$, respectively, for these three states.
