Ma. Lone et Py. Wong, NEUTRON YIELDS FROM PROTON-INDUCED SPALLATION REACTIONS IN THICK TARGETS OF LEAD, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 362(2-3), 1995, pp. 499-505
Total neutron yield, integrated over the neutron energy and emission a
ngle, is calculated for spallation reactions in lead at proton energie
s between 0.4 and 2 GeV. The computations were made with the LAHET/MCN
P code package using the intranuclear-cascade-evaporation model of Ber
tini. The dependence of the integral neutron yield on the target dimen
sions is investigated and the contribution from the (n, xn) interactio
ns 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 targ
et is calculated to be in the range of 46 to 57 n/p, depending on the
level density parameter used in the evaporation model.
