Breakup of 33.4MeV/u ¹⁷N on a ⁹Be Target

Correlation measurements of neutrons and fragments have been performed in a reaction of 33.4MeV/u ¹⁷N on a ⁹Be target. Energy spectra of n and nitrogen fragments were obtained at different angles. Based on the nuclear diffraction dissociation model, the measured energy spectra and the neutron angular distributions were reproduced quite well assuming that ¹⁷N was composed of ¹⁶N and n or ¹⁵N and 2n interacting with the nonlocal separable potential. The satisfactory agreement between the theoretical calculations and the experimental data shows that the contribution of Coulomb dissociation is negligible in the reaction concerned.
