Assuming that the range of nuclear forces is small compared to the size of the triton and the wavelength of the incoming neutron ( zero-range'' approximation), a connection is derived between the cross sections for elastic and inelastic n-t scattering by calculating the ratio of the first Born approximation for inelastic to that for elastic scattering. A calculation of the inelastic scattering cross section is made for an incoming neutron energy of 14 Mev. Since experimental elastic angular distributions are not available, values calculated by Bransden and Robentson for p- He/sup 3/ assuming Serber interaction are used. Inelastic angular distributions are calculated for the ejected deuteron, the ejected neutron, and the scattered neutron. Integrating over the distnlbution of the ejected deuteron, a value for the total n-t inelastic cross section of 343 mb is obtained. (auth) |
