Abstract： Measurements of the total reaction cross section for 12-16C, 14-17N and 16-18O on carbon target at intermediate energies were performed on RIBLL of HIRFL. A larger enhancement of σR for 15C was observed than that for its neighbors. The analysis of these data indicates possible existence of an anomalous nuclear structure in 15C. A new quantity was suggested as the criterion to distinguish anomalous structure nuclei from normal nuclei.
