摘要
应用放化法首次测量了 ̄(252)Cf自发裂变中 ̄(114)pd的累计裂变产额,其值为(2.50±0.11)%。为了解决有关 ̄(252)Cf自发裂变质量分布精细结构方面存在的分歧,还测量了 ̄(112)pd和 ̄(113)Ag ̄g的累计产额,并应用最新的核参数对文献中其它作者的数据进行了重新处理和评价。结果表明,在质量分布A=113处存在精细结构。
The radiochemical methd is for the first time used to measure the cumulative fission yield of ̄(114)Pd in  ̄(252)Cf spontaneous fission,A value of(2.50±0.11)%is obtained.In order to solve the discrepancy on the existence of fine structure in the mass distribution of ̄(252)Cf spontaneous fission,the cumulative yields of ̄(112)pd and ̄(113)Ag ̄g are also measured.All these results and other availabledata are re-corrected and evaluated using the latest nuclear data. It is shown that there exists afine structure peak on the mass distribution curve at A = 113.
