Fluctuation measurement of excitation function in the dissipative process of 19F + 51V reaction

Excitation functions of the projectile-like fragments in the dissipative reaction 19F + 51V have been measured from 102.25 MeV to 109.50 MeV in 250 keV steps. The corresponding energy coherence widths Γ were extracted by means of the energy autocorrelation function method. The dependence of Γ on the degree of freedom of neutron excess NZ and the dependence of the charge number Z on the angular momentum coherence width γ are presented and discussed.
