Abstract

The 48Ti on 40Ca reactions have been studied at 300 and 600 MeV focusing on the fusion-evaporation (FE) and fusion-fission (FF) exit channels. Energy spectra and multiplicities of the emitted light charged particles have been compared to Monte Carlo simulations based on the statistical model.

Highlights

  • Experimental data are compared with events produced through Monte Carlo simulations where complete fusion events are generated with a triangular spin distribution for the compound nuclei (CN) up to l0

  • The forward chamber of the GARFIELD apparatus [6, 7] was the main detector for the light charged particles (LCP) emitted in the reaction

  • The LCP multiplicities in coincidence with an ER are shown in Table 2 for the two measured energies and they are compared to statistical model predictions

Summary

Introduction

Decay of the excited compound nuclei (CN). With this in mind and considering that not many data in this region exist from exclusive measurements [2,3,4], we performed an experimental campaign at the Tandem-ALPI complex of the Laboratori Nazionali di Legnaro. The reactions have been analyzed focusing on the fusion-evaporation (FE) and fusion-fission (FF) exit channels, which dominate in mass-symmetric collisions at moderate bombarding energies. For excitation energies up to around 3 MeV/u the equilibrium of the internal degrees of freedom is reached in shorter times compared to evaporation and fission time scales. The output of the simulation is filtered through solid angle acceptance and particle energy detection thresholds of the experimental apparatus
