On the mechanism of the (n, 2n) reaction with 14MeV projectiles on127I and209Bi

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

The angular and spectral distributions of coincident neutrons from the reactions127I(n, 2n)126I and209Bi(n, 2n)208Bi have been measured with two time-of-flight detectors at the incident energy 14.1 MeV. Neutron emission has been studied for reaction anglesθ lab between 10° and 150° (relative angles from 60° to 270°). Energy spectra, angular distributions and coincidence yields are compared with statistical model calculations including preequilibrium decay modes, and nuclear level density and spin cut off parameters are derived.
