摘　　要：应用扰动法提取和研究了紧束缚体系^(16)O+^(208)Pb和弱束缚体系^(9)Be+^(208)Pb灵敏区域。首次区分了对应于形状散射和共振散射对应的灵敏区域。同时,发现紧束缚体系和弱束缚体系的灵敏区域都存在着强烈的能量相依性:在垒上区域,灵敏区域在强吸收半径附近变化;而在垒下能区,灵敏区域与纯库仑场中的最趋近距离有相似的变化趋势。With the application of the notch technique,the radial sensitive regions for the tightly bound system^(16)O+^(208)Pb,and weakly bound system^(9)Be+^(208)Pb were investigated.It is the first time that the shape and resonant scattering can be identified from the sensitivity functions.Moreover,strong energy dependence of sensitive regions were found for both the tightly and stable weakly bound systems:in the above barrier region,the sensitive region varies around the strong absorption radius;while below the barrier,the behavior of sensitive region is close to that of the closest approach in the Coulomb field.
