摘　　要：应用透射法对中能区F同位素与C靶的反应总截面进行了测量 .发现17F的反应总截面比其邻近同位素的反应总截面稍有增强 .用Glauber模型和BUU模型对F同位素进行了差异因子d的分析 .17F的差异因子d比其附近同位素稍有增强 .分析结果表明17F可能存在质子皮结构 .The reaction cross sections σ R of F isotopes on carbon target were measured at intermediate energies via the transmission method. It was found that the reaction cross section of 17F has a little enhancement compared with that of its neighbor isotopes. The difference factor d has been deduced from the measured σ R by using the BUU model and Glauber model. It is enhanced also for 17F compared with its neighbor isotopes. From the above analysis, a possible proton skin structure is suggested for 17F.
