Abstract：
In this paper,the results of two-proton interferometry obtained in the experiment of 46.7 MeV/u ¹²C+⁵⁸Ni,¹¹⁵In,¹⁹⁷Au have been discussed. The influnce of nuclear force, Couloumb force and Fermi statistics on the correlation function is discussed also. The source radius parameters ro obtained from the experiment increase withincreasing of the target nuclei mass. In the experiment, the p-p correlation function seems to have a strong dependencs on the sum energy of two correlated protons. The ro parameter decreases with increasing of the sum energy, indicating that the high energy protons are mainly from the nonequilibrium emission process.
