摘要
The energy spectra of intermediate mass fragments (IMF) emitted in 30 MeV/u Ar-40 + In-115 reaction has been measured. After analyzed the energy spectra of the same kind of IMF emitted at different angles, the dependence of emission mechanism of IMF on the emission angles has been obtained. Assumed that the speed of the moving sources and the Coulomb energies do not change with the emission angles, the moving sources fitting of the measured energy spectra have been completed by changing the intensities and the temperature parameters of the emission sources. The evolution of the portions and intensities of three different emission sources as a function of the emission angles has been discussed.
