Abstract
We have been carrying out systematic random stopping power experiments in the low velocity region (v0 to 5v0, where v0 is the Bohr velocity) using heavy ions (Z1 = 8 to 29). The objective is to supplement in a significant way the currently available scanty data in this region. In order to optimise the data collection for a variety of heavy·ions, we have used our recently developed technique of adopting a twin detector in conjunction with Elastic Recoil Detection Analysis (ERDA) technique. In continuation, we now report energy losses of Si, Fe, Ni and Cu ions in carbon foil in the energy range 0.1-1.1 MeV/u. Here we are reporting experimental stopping power data for Ni ions in the velocity region of 0.1-0.6 MeV/u. Most of the experimental data have an error of around 6%. Comparison of the now available data have been made with existing theoretical and semiempirical models.
