Abstract

The cross section measurements of 17 neutron induced reactions using an intense sem: monoenergetic neutron field were recently reported. Neutrons for energies up to 40MeV wer produced by a simple Be target system bombarded by protons of 9 different energies betwee 20 and 40 MeV. Successively in this neutron field, we measured the cross sections of 15 reactions c natMg(n, Xnp)24Na, natSi(n, Xn2p)27Mg, natSi(n, Xnp)28Al, natSi(n, Xnp)29Al, natCa(n, Xnp)42K natCa(n, Xnp)48K, natV(n, Xn2p)46Sc, natV(n, Xn2p)47Sc, natCr(n, Xnp)52V, natCr(n, Xnp)53v natCu(n, Xn2p)62mCo (T1/2=14 min), natZn(n, Xn2p)65ni, natZn(n, Xnp)64Cu, natZ(n, Xnp)66Cu, and natZn(n, Xnp)68mCu (T1/2=3.8 min) by irradiating natural samples of Mg, Si, Ca, V, Ci Cu and Zn. The excitation functions of these reactions were obtained by using the least squares fitting (LSF) of the cross-section values calculated with the AL1CE/LIVERMORE8 code, and also by using the SAND-II and the NEUPAC unfolding codes with the initial gues values derived from the LSF results and empirical reference data. © 1994 Taylor & Francis Ltd.
