本文就LiF晶体中O~(--)对于F_2~+心的稳定作用,进行了理论研究。作者根据文中提出的能量循环关系图,采用HWW模型和点电荷模型,应用量子力学的微扰方法,求出O~(--)于F_2~+心能态影响的一般表式。其结果表明,O~(--)不仅使F_2~+心的电子亲和能下降,而且使F_2~+心的结合能增加,正是这两方面的因素,使得掺氧LiF晶体中F_2~+的稳定性提高。文中报告了LiF晶体中O~(--)对于F_2~+心稳定能的理论值,并同实验值进行了比较,在所选择的参数条件下,两者很好地吻合。本文所报告的工作,尚未见有文献报导。
In this paper, LiF crystal O ~ (-) for F_2 ~ + heart stability, a theoretical study. Based on the energy cycle diagram proposed in this paper, the author uses the HWW model and the point charge model, and applies the perturbation method of quantum mechanics to get the general expression of the energy state of O ~ (-) at F_2 ~ +. The results show that O ~ (-) not only decreases the electron affinity of F_2 ~ + hearts, but also increases the binding energy of F_2 ~ + hearts. It is these two factors that make F_2 ~ + Stability improved. In this paper, the theoretical value of O ~ (-) for F_2 ~ + in the LiF crystal is reported and compared with the experimental data. Under the selected parameters, the two are in good agreement. The work reported in this article has not been reported in the literature.
