Excitation functions for projectile-like fragments from F-19+V-51 reaction have been measured at 102.25 to 109.50MeV in 250keV steps. A TOF+(Delta E - E) telescope at theta(L) = 21.7 degrees is used to identify atomic number Z and mass number A of ejectiles simultaneously. Fluctuations of the dissipative cross section for a. series of isotopes are observed. Their coherence energy widths are extracted by generalized statistical fluctuation analysis and the dependence on mass number and on N/Z values are observed for the first time.
