Deep-inelastic reactions of 16O+48Ti at 100 MeV.

Abstract

The particle-inclusive doubly differential cross section, ${d}^{2}$\ensuremath{\sigma}/dE d\ensuremath{\theta}, for ejectiles with atomic numbers Z=4 to 15 from 100 MeV $^{16}\mathrm{O}$${+}^{48}$Ti, was measured over a large angular range. From a semiclassical analysis of the angular distributions we obtain the mean values and the dispersion widths of the deflection angles and the contributions from orbiting around 180\ifmmode^\circ\else\textdegree\fi{}. A mean prolate deformation with \ensuremath{\beta}=0.37 is derived from the most probable Q values in the fully damped processes at large angles. Using the surprisal technique, the shapes of the energy spectra are well reproduced by constrained phase-space distributions. If the measured correlation of the angular momentum transfer and the reaction Q value is taken into account, only the mean Q values of the quasielastic and of the deep-inelastic reaction component are required as constraints.
