Measurement of the 160Gd(p,n)160Tb excitation function from 4–18 MeV using stacked-target activation

Abstract

The 160Gd(p,n)160Tb excitation function was measured between 4–18 MeV using stacked-target activation at Lawrence Berkeley National Laboratory’s 88-Inch Cyclotron. Nine copper and eight titanium foils served as proton fluence monitor foils, using the natCu(p,x)65Zn, natTi(p,x)48V, and natTi(p,x)46Sc monitor standards, respectively. Variance minimization using an MCNP v.6.2 model reduced the systematic uncertainties in proton energy and fluence. A priori predictions of the 160Gd(p,n) reaction using ALICE, CoH, EMPIRE, and TALYS, as well as the TENDL database, are compared to the experimentally measured values.
