摘要
用ＨＰＧｅ直接γ射线能谱法绝对测定热中子和８ＭｅＶ中子诱发２３５Ｕ裂变的２０个产物的产额．其中１９个是链产额，１个是独立产额．绝对裂变率是用双裂变室测定的，并测定１９８Ａｕγ射线的活度检验裂变率测定的可靠性．
mass cumulative yields and 1 independent yield are obtained for fission of 235 U induced by 8 MeV neutron. All of them are determined absolutely. Fission product activities are measured by HPGe γ ray spectrometry of irradiated 235 U foils. The 235 U targets are attached to double fission chamber containing two thin, standardized deposits of 235 [KG*8/9]U to monitor the fission rate absolutely. Activities of 198 Au are measured to verify the reliability of the double fission chamber.
