摘要Excitation functions have been measured for different projectile-like fragments produced in 27Al19F,x)y reactions at incident energies from 110.25 to 118.75MeV in 250keV steps. Strong cross section fluctuations of the excitation functions are observed. The cross-correlation coefficients of the excitation functions for different atomic number Z and for different scattering angle θcm have been deduced. These coefficients are much larger than the statistical theoretical calculated ones. This indicates that there are strong correlations between different exit channels in the dissipative heavy ion collision of 27Al(19F,x)y.
