Total neutron yield, integrated over the neutron energy and emission angle, is calculated for spallation reactions in lead at proton energies between 0.4 and 2 GeV. The computations were made with the LAHET/MCNP code package using the intranuclear-cascade-evaporation model of Bertini. The dependence of the integral neutron yield on the target dimensions is investigated and the contribution from the (n, xn) interactions of neutrons of energy < 100 MeV is evaluated. For 1.6 GeV protons, the integral neutron yield from a 100 cm diameter, 100 cm long Pb target is calculated to be in the range of 46 to 57 n p, depending on the level density parameter used in the evaporation model. © 1995.
