本文研究了He原子在狭窄空间中形成二聚体的过程,阐明了吸附势的影响。结果用有效半径<ρ>和单粒子基态波函数宽度Δρ很好地解释了。对于~ 3 He,吸附势在低温时促进二聚体的形成,而在低温时则不利于二聚体的形成。在此基础上,我们讨论了最近有关3 He原子在纳米孔中的实验结果.
Dimer formation by He atoms confined in a narrow tube is studied and the effect of adsorption potential is clarified. The results are well explained in terms of the effective radius <ρ> and the width of the single-particle ground-state wave function Δρ. For3He, adsorption potential promotes dimer formation whenÅ, but is unfavorable whenÅ. We discuss the recent experimental results for3He atoms confined in nanopores in light of the present results.
