【摘要】用半导体探测器测量了7—5MeV/A的¹⁴N在⁵⁹Co和⁵¹V靶上的弹性散射能谱和角分布。定出了靶中重元素沾污的种类和绝对量。用广义菲涅耳模型拟合了弹散角分布,讨论了从拟合弹散角分布提取准弹截面的可能性。更多还原

【Abstract】 The energy spectra and angular distributions induced by 7—5 MeV/A ¹⁴N on ⁵⁹Co and ⁵¹V are measured by using semiconductor detector. The atomic numbers and quantities of the contamination heavy element are determined. The angular distributions of the elastic scattering are fitted by using General Fresnel model. The possibility of extracting the quasi-elastic cross section from the fitting procedure is discussed.更多还原
