在北京HI-13串联加速器实验室的GIRAFFE装置上，采用一种新颖的厚靶法对12C+p的弹性共振散射进行了逆运动学研究。反冲质子由基于大面积双面硅条探测器的ΔE-E反望远镜测量，实验角度在θ0 = 15°左右。得到了12C（p,p）弹性散射在Ec.m = 0.31-3.45 MeV的较宽能量范围内的激发函数，用已知13N核前三能级共振参数的r矩阵计算很好地解释了这一结果。结果表明，该装置可直接应用于二次放射性光束的弹性共振散射研究。
The elastic resonance scattering of 12C+p has been studied in inverse kinematics via a novel thick target method at GIRAFFE facility of HI-13 tandem accelerator laboratory, Beijing. The recoil protons were measured by a ΔE-E counter telescope based on a large area double-sided silicon strip detector at laboratory angles around θ0 = 15°. The excitation function for 12C(p,p) elastic scattering has been obtained over a wide energy range of Ec.m.=0.31–3.45 MeV, which was explained quite well by the R-matrix calculation with known resonance parameters of the first three levels in 13N nucleus. Thus it is demonstrated that the present setup can be directly applied to the study of elastic resonance scattering with secondary radioactive beams.
