The investigation of ¹⁶O states by the ${}^{15}\text{N}\text{(}\text{d}\text{,}\text{n}\text{)}{}^{16}\text{O}$ reaction

Abstract

Using the pulsed beam, neutron time-of-flight method, polarization angular distributions for thirteen states in ¹⁶O have been measured for the ${}^{15}\text{N}\text{(}\text{d}\text{,}\text{n}\text{)}{}^{16}\text{O}$ reaction at a deuteron energy of 4.83 MeV. The differential cross section for elastic scattering of deuterons from ¹⁵N was analyzed using the optical-model formalism to provide initial-state wave functions for distorted-wave method calculations of the ${}^{15}\text{N}\text{(}\text{d}\text{,}\text{n}\text{)}{}^{16}\text{O}$ reactions. These calculations were compared to experimental differential cross-section and polarization data and were used for an analysis of P(θ)σ(σ). The agreement between experiment and calculations is fair for most of the states. The summed particle strengths and energy centroids were calculated for several particle states and were compared to shell-model calculations.
