Value of equilibrium charge states distribution width for parametrization of heavy recoil spectra

摘要

Energy and time-of-flight spectra of heavy nuclei were calculated using PC-based code with q(sup 2) scaling of the stopping force in the low pressure hydrogen filling the working volume of the gas-filled separator at a pressure of about 1 Torr. (chi)(sup 2) distribution is used to describe the charge states. The measured recoil spectra which are used to extract the optimum parameter of equilibrium charge states distribution width were obtained in heavy ion induced (sup 197)Au + (sup 22)Ne and (sup nat)W + (sup 34)S reactions. 13 refs., 5 figs.
