应用自制的单光子计数装置系统地测量了238Pu激励下的Ne光谱，辨认出Ne谱线33条，其中31条与电激励的结果一致，而664.0 nm和711.6 nm两条谱线在电激励条件下未见报道。根据原子分子反应静力学原理，对实验得到的玻耳兹曼(Boltzmann)图进行了分析，提出了实现核泵浦Ｎｅ激光的复合离解反转机制。

A systematic study of the spectra of neon by nuclear impaction is reported. Asingle photon counting system designed and set up by ourself has been used to measure thespectra of neon excited by alpha particles emitted from 238Pn. Thirty three of neontransition lines are identified, two of them, i. e. 664.0 nm and 711.6 nm are probablydue to the transitions 3s4-3p4 and 4d2-2pl respectively, which has not been observedin the neon spectra by electronic impaction. Based on the Atomic and Molecular Reaction statics, the so-called dissociative recombination inversion mechanism in nuclear pumped laser is proposed and fairly proved by our works for the first time.
