Abstract

The complete-fusion reaction 204Pb(48Ca,2n)250No was used to study two activities of 250No with distinct half-lives. A total of 1357 events were observed in the SFiNx neutron detection system. The average number of neutrons emitted per spontaneous fission of 250No was determined to be . The unusually symmetrical shape of the prompt neutron multiplicity distribution was restored and presented for the first time. Statistical tests were performed to compare the prompt neutron multiplicity distributions associated with the ground state and K-isomer state decays.

与基态和同分异构态衰变有关的 250No 自发裂变中的中子快速发射

利用完全聚变反应 204Pb(48Ca,2n)250No 来研究具有不同半衰期的两种 250No 活性。SFiNx 中子探测系统共观测到 1357 个事件。经测定，250No 每次自发裂变发射的中子平均数为。首次还原并展示了瞬发中子倍率分布的异常对称形状。对与基态和 K-异构态衰变相关的瞬发中子倍率分布进行了统计检验比较。
