Study of evaporation spectra of protons and alpha particles from compound nuclei in mass region=110

We have recorded proton and alpha spectra at various backward angles between 110 to 170 degrees in case of the following reactions: (70,85,103 MeV) 19F + 93Nb. Silicon surface barrier detector telescopes of thickness (15μm, 1 mm), (25μm, 2 mm), (40μm, 2 mm) have been used in order to record these spectra. Each spectra has been normalised by using Rutherford scattering data obtained from a monitor detector placed at a fixed forward angle. Each of these laboratory spectra has been converted into centre of mass system in order to extract the emission barriers, temperatures and the level density parameters. Mean centre of mass energy for each spectrum is obtained and is compared with the statistical model code Pace2. (author). 2 refs., 2 figs., 1 tab
