摘要:

用活化技术研究了天然钯和富集钯样品在Ep =2.75 ~ 9 MeV能量范围内的质子活化反应。我们测定了~(102)Pd(p,γ)~(103)Ag、~(104)Pd(p,γ)~(105)Ag和~(105)Pd(p,n)~(105)Ag的截面,以及~(104)Pd(p,n)~(104)Ag ~(104)、~(105)Pd(p,γ)~(106)Ag ~(106)、~(106)Pd(p,n)~(106)Ag ~(106)和~(110)Pd(p,γ)~(105)Ag的部分截面。n)110Ag^m,不确定度在3%到15%之间,用于限制理论豪泽-费什巴赫速率和直接用于伽马过程计算。

英文摘要:

Proton-activation reactions on natural and enriched palladium samples were investigated via the activation technique in the energy range of E_p=2.75 MeV to 9 MeV, close to the upper end of the respective Gamow window of the gamma process. We have determined cross sections for 102Pd(p,gamma)103Ag, 104Pd(p,gamma)105Ag, and 105Pd(p,n)105Ag, as well as partial cross sections of 104Pd(p,n)104Ag^g, 105Pd(p,gamma)106Ag^m, 106Pd(p,n)106Ag^m, and 110Pd(p,n)110Ag^m with uncertainties between 3% and 15% for constraining theoretical Hauser-Feshbach rates and for direct use in gamma-process calculations.
