The in-medium effects in nucleon-nucleon cross-section were treated using different approaches. We study the variation of σR with different values of rms. Also we study the variation of sR with different values of incident energy per projectile nucleon for light interacting pair 12C-12C and heavy target nucleus pair12C-208Pb. The coulombs repulsion was taken into consideration by assuming a simple model. We found that the in-medium effects on σR are small when the target nucleus becomes heavy.

Radioactive ion beams were produced through the projectile fragmentation induced by 69MeV/nucleon 36 Ar primary beam on a 9 Be target. Measurements of reaction cross section (σR) for some proton-rich nuclei on carbon target at intermediate energies around 30MeV/nucleon have been performed on RIBLL of HIRFL by transmission method and transmission plus transportation method. The experimental σR values for 23Al and 27P are abnormally large compared with their neighboring nuclei and that of 17F has an enhancement compared with the neighboring isotopes. It suggests anomalously large matter root-mean-square radii and proton halo structure in 23 Al and 27 P . The experimental σR values and momentum distribution of fragmentation reaction product for 31 Cl , 32 Cl , 33 Cl , 28 S , 29 S were performed also on RIBLL by transmission and transportation method. These data are in analyzing. The calculation of relativistic density-dependent Hartree shows that the nuclei 23 Al , 27 P , 31 Cl may have proton-halo structure and 17F, 32Cl may have proton-skin structure. New experiment on the search for new nuclides 25 P and 26 S in proton drip line is also described. The significance of these measurements and possible proton halo and skin for light proton-rich nuclei has been discussed.
