我们寻找弱结合的He-He-K分子的存在，其中结合能预计是开氏度的数量级。利用每对粒子之间的最佳经验相互作用，在绝热近似下使用超球坐标求解三原子系统的薛定谔方程。分别发现He-4-He-4-K-39、He-4-He-3-K-39和He-3-He-3-K-39三聚体中的每一个的结合态。He-3-He-3-K-39分子的束缚态是在现实分子系统中发现的晕态，因为He-3-He-3和He-3-K-39二聚体中都没有束缚态。
We search for the existence of the weakly bound He-He-K molecules where the binding energies are expected to be of the order of degrees Kelvin. By employing the best empirical interaction between each pair of particles, the Schrodinger equation for the triatomic systems is solved using hyperspherical coordinates in the adiabatic approximation. A bound state is found for each of the He-4-He-4-K-39, He-4-He-3-K-39, and He-3-He-3-K-39 trimers, respectively. The bound state for the He-3-He-3-K-39 molecule is the halo state found in realistic molecular systems for there are no bound states in both the He-3-He-3 and He-3-K-39 dimers.
