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

The  Gd(p,n)Tb 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  Cu(p,x)Zn,  Ti(p,x)V, and  Ti(p,x)Sc monitor standards, respectively. Variance minimization using an MCNP v.
