Analysis of the 14N+12C heavy-ion reaction

The 14N (E/sub lab/ = 106 and 167 MeV) +12C heavy-ion reaction is analyzed in terms of a modified version of the semiclassical scattering model of Broglia followed by an evaporation calculation. The deflection and energy loss functions are taken from recent time dependent Hartree-Fock calculations. The complete fusion amplitude vs the angular momentum l is obtained phenomenologically. A comparison between the model predictions and experiment is made for the following quantities: the total integrated cross sections for production of a fragment with given Z, sigma(Z); energy distributions (d2sigma/dΩdE)/sub Z/ at fixed laboratory angle and fragment charge; angular distribution (dsigma/dΩ)/sub Z/ at fixed fragment charge Z and integrated over energy. The agreement is satisfactory. It is noted that the Z spread observed in this reaction can be described by using only evaporation effects in the highly excited reaction fragments produced in the original inelastic collision
