Abstract：
The yield of light charged particles (LCPs) emitted at forward angles is investigated in the reactions of Si target bombarded by the fragments produced in the fragmentation of 69AMeV ³⁶Ar. It is found that the yield of LCPs increases with decreasing the neutron number of fragment isotopes,and for the lighter fragments,the effect is more prominent. Moreover the yield of LCPs decrease with the increase of the proton number of fragments with the same isospin. It indicates that the yield of LCPs is very sensitive to the structure of the nuclei near the proton drip line. It can be regarded as a possible probe to explore the structure of proton rich nuclei and a new way to provide an evidence for existing proton halo.
