摘 要: 利用17F次级束轰击 (CH2)n厚靶,通过17F+p弹性道布居18Ne质子发射阈之上的能级,得到了Ec.m.=0.5~1.7 MeV 区间弹性共振散射1H(17F,p)17F 的激发函数。利用R矩阵论程序MULTI7对实验的激发函数进行分析,导出了18Ne 能级的质子宽度等信息。
关 键 词: 核结构;18Ne 能级;弹性共振散射;激发函数;厚靶技术

Abstract: The 17F+p elastic resonance scattering was studied with a radioactive secondary beam 17F bombarding a (CH2)n thick target. The experimental excitation function for the 17F+p elastic resonance scattering was obtained within the energy interval of Ec.m.=0.5~1.7 MeV. By analyzing the excitation function with a multilevel R-matrix code MULTI7, properties of the levels in 18Ne including the proton width were deduced.
Key words: nuclear structure; energy levels in 18Ne; elasticresonance scattering; excitation function; thick�target technique
