Abstrakt

We present a novel method to measure excitation functions and angular distributions in alpha-particle scattering. The method is based on the well-known principle of backscattering from a thick target. It allows measuring the desired energy range in fairly large laboratory-energy steps, and it records the excitation function continuously in energy. Some examples from alpha+Si-28 elastic and alpha+Mg-24 elastic and inelastic scattering are given to illustrate the method. It is well-suited for detailed measurements of excitation functions for alpha-particle energies around 20-30 MeV, where so far most measurements have been made in fairly large energy steps.
