~(nat)W(p,xn)~(181─186)Re反应的激发函数

摘要: 使用叠靶技术测量了２２．５ＭｅＶ的质子照射天然钨时生成~（１８１）Ｒｅ、~（１８２）Ｒｅ~ｍ、~（１８２）Ｒｅ~ｇ、~（１８３）Ｒｅ、~（１８４）Ｒｅ~ｍ、~（１８４）Ｒｅ~ｇ和~（１８６）Ｒｅ的激发函数。估算了~（１８６）Ｗ（ｐ，ｎ）~（１８６）Ｒｅ反应生产用于治疗的放射性核素~（１８６）Ｒｅ的厚靶产额，并与~（１８６）Ｗ（ｄ，２ｎ）~（１８６）Ｒｅ反应的有关数据进行了比较。

Abstract: EXCITATION FUNCTIONS FOR~(nat)W(p，xn)~(181─186)Re REACTIONSLi Wenxin;He Weiyu;Yin Duanzhi;Qiu Xuejun;Qian Jun;Hu Weiqing(Shanghai Institute of Nuclear Research，the Chinese Academy of Sciences，Shanghai 201800) Abstract:The excitation functions are determined for the products of~(181) Re，~(182)Re~m，~(182) Re~g，~(183) Re，~(184)4Re~m，~(184)Re~g and~(186)Re produced from proton-induced reactions on natural tungsten at energies up to 22． 5 MeV by stacked-foil technique，The thick target yield of~(186)Re is estimated via~(186)W(p，n)~(186)Re reaction and is compared with that of~(186)W(d，2n)~(186)Re reaction reported elsewhere.Keywords: ~(nat)W(p，xn)~(181─186)Re,Excitation function,Yield of~(186)Re
