摘要

Measurements of the total reaction cross sections (σR) for some proton-rich nuclei(N=11-15 isotones) on a carbon target at intermediate energies have been performed on the Radioactive Ion Beam Line of the Heavy Ion Research Facility in Lanzhou. A larger enhancement of σR for 27p has been observed than for its neighbours.Evidence for a proton halo in 27p has been revealed in the Glauber analysis of the total reaction cross sections in terms of the difference factor d.
