摘要

An empirical expression has been obtained for double differential neutron yield distributions from proton induced reactions on thick stopping targets. Calculated neutron yield distributions using an exciton (hybrid) nuclear reaction model have been used to generate polynomial expressions relating neutron yield distributions (emission energy and angle) with incident proton energy and target mass. The present expression is obtained by fitting data for 39 elements from ~9Be to ~(209)Bi and for incident proton energies from 25 to 200 MeV.
