| Abstract | Radioactive ion beams were produced through the projectile fragmentation induced by 69MeV/nucleon Ar-36 primary beam on a Be-9 target. Measurements of reaction cross section (sigma(R)) 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 sigma(R) values for Al-23 and P-27 axe abnormally large compared with their neighboring nuclei and that of F-17 has an enhancement compared with the neighboring isotopes. It suggests anomalously large matter root-mean-square radii and proton halo structure in Al-23 and 27P. The experimental sigma(R) values and momentum distribution of fragmentation reaction product for Cl-31, Cl-32, Cl-33, S-28, S-29 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 Al-23, (27)p, Cl-31 may have proton-halo structure and 17F, Cl-32 may have proton-skin structure. New experiment on the search for new nuclides P-25 and S-26 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. |
