The cumulative and independent yields of various fission products within the mass range of 83–155 have been measured in the thermal neutron induced fission of ²³⁸Pu by using an off-line γ-ray spectrometric technique. From the cumulative yields, post-neutron mass chain yields were obtained by using the charge distribution correction. From the mass yields data, the full width at tenth maximum (FWTM) of light and heavy mass wing, the average light mass (<A_L > ) and heavy mass (<A_H > ) as well as the average number of neutrons (<ν > ) emitted were obtained. The mass yield data in the ²³⁸Pu(n_th, f) reaction was compared with the similar data of ²⁴¹Pu(n_th, f) reaction to examine the nuclear structure effect.

在²³⁸ Pu的热中子诱导裂变中，使用离线 γ 射线光谱技术测量了 83-155 质量范围内各种裂变产物的累积和独立产率。从累积产率中，通过使用电荷分布校正获得中子后质量链产率。由质量产率数据可知，轻质和重质翼的第十大宽度（FWTM）、平均轻质（<A _L  > ）和重质（<A _H  > ）以及平均中子数（ <ν > ) 发射得到。将²³⁸ Pu(n _th , f) 反应的质量产率数据与²⁴¹ Pu(n _th, f) 检查核结构效应的反应。
