A millimicrosecond time-of-flight technique was applied to the study of (p,n) reactions in K, Ca/sup 48/, Ti, Cr, Mn, Fe, Cu, As, and Rb using the phase- focused 3-Mev proton beam from a small fixed-frequency cyclotron. The neutron spectra. resulting from these reactions. gave data from which the ground-state Q values and some of the energy levels in the residual nuclei have been determined. The reactions in K and Fe yielded only one neutron group each, which corresponded to the ground states in Ca/sup 41/ and Co/sup 57/, respectively. In addition to the ground state Q values. the energies were determined for one excited state in each of the nuclei Mn/sup 53/, Mn/sup 54/, and Sr/sup 85/, two excited states in Zn/sup 65/, three excited states in Sr/sup 87/, and four excited states in each of the nuclei Sc/sup 48, V/sup 49/, Fe/sup 55, and Se/sup 75/. The angular distribu tions of the neutron groups were observed to be essentially isotropic in the Ca/sup 48/(p,n)Sc/sup 48/ and Cu/sup 65/(p.n) Zn/sup 65/ reactions. (auth)
