基于新测出的34Cl核共振能级的核物理信息,本文分析了在新星环境下33S(P,γ)34Cl的热核反应.本工作中同时考虑了非共振、共振两翼和窄共振对热核反应率的贡献,新星环境下33S(P,γ)34Cl的热核反应率的较统计模型给出的结果明显减少,最多可下降约25%.结果可能影响到对新星抛射物中S同位素比率的预测(例如32S/33S),而这个比率可能会被用作新星前身星的一个诊断工具.
Based on the new measured nuclear physics information of the resonant states of 34Cl,this paper calculated the thermonuclear 33S(P,γ)34Cl rate in ONe novae.Our calculation improved the precision of the thermonuclear 33S(P,γ)34Cl rate in ONe novae,because the result included the contribution from Non-Resonant,Narrow-Resonance and Broad-Resonance,which may affect the prediction of the sulphur isotopic in the ejecta of novae(e.g.32S/33S)that may be used as diagnostic tools for the nova.
