以１２￣Ｃ（４７ＭｅＶ／ｕ）＋１９７￣Ａｕ靶，通过化学分离及γ谱学方法获得了Ｉｒ和Ｐｔ同位素产额。用测到的Ｐｔ累积产额对相应Ｉｒ同位素做了照射期内母体衰变修正，从而获得了很好的Ｉｒ同位素分布。讨论了Ａ＞１７０丰中子核产生截面、截面的Ｑｇｇ系统性和剩余激发能的问题。 Ir and Pt isotope yields were obtained by chemical separation and gamma spectroscopy at 12 ° C (47 MeV / u) + 197 ~ Au target. The measured Ir accumulation of the corresponding Ir isotopes made during the irradiation of the parent decay correction, resulting in a good Ir isotope distribution. The problems of cross section, cross section Qgg system and remaining excitation energy of A> 170 abundance neutron nucleus are discussed.
