AI总结:

利用叠层箔活化技术测量18 MeV以下质子在114Sn、120Sn靶上的反应截面及同质异能截面比,并与已有实验和Talys1.95计算比较。

摘要:

我们采用叠层箔活化技术,测量了能量高达18 MeV的质子在锡上引发反应的截面,并报道了114Sn(p,α)111In、120Sn(p,α)117gIn和114Sn(p,x)113Sn反应的首批实验值。测得的截面已与现有实验值以及基于Talys1.95的数值计算进行比较。我们的数据与所有先前实验吻合良好,也与Talys1.95结果一致,但120Sn(p,α)117m,gIn反应除外,其数值计算向更高能量偏移。我们还测量了117m,gIn和120m,gSb对的同质异能截面比随入射质子能量的变化。

英文摘要:

We measure cross sections of proton-induced reactions on tin up to energies of 18 MeV using the stacked-foil activation technique, and report first experimental values for 114Sn(p,α)111In, {^{120}}Sn(p,α)117gIn, and 114Sn(p,x)113Sn reactions. Measured cross sections have been compared to existing experimental values and numerical calculations based on Talys1.95. Our data are in good agreement with all previous experiments, and also with Talys1.95 results except for 120Sn(p,α)117m,gIn reactions where the numerical calculations are shifted to higher energies. We also measure isomeric cross section ratios for 117m,gIn and 120m,gSb pairs as functions of the incident proton energy.
