Résumé

The "first chance" spectra of light charged particles and neutrons emitted from ¹⁶⁰Yb produced in the ⁶⁰Ni+¹⁰⁰Mo reaction have been isolated. The same initial temperature for the different evaporated particles and a decrease of the Coulomb barriers for the charged particles are observed. The inverse level density parameter K= A/ a reaches a value of 13.8±0.7 MeV at E_TH≈236 MeV, confirming the decrease of the parameter a at excitation energies above 150 MeV.
