Cross-section fluctuation of the isotope projectile-like fragments in the dissipative reaction F-19+V-51

By using a detection system combining the time-of-flight (TOF) method with the Delta E-E technique, the excitation functions, the dependence of the dinuclear system's energy coherence widths Gamma on the product mass number A and on the product degree of freedom of neutron excess N/Z for some elements and their isotopes in the dissipative reaction (1)9F+V-51 at energies from 102.25 MeV to 109.50 MeV (in 250 keV steps) were presented and discussed for the first time.
