The quantum second virial coefficient B_q has been used as a tool to quantify the average magnitude and sign of interactions between T↓ atoms. A negative B_q represents an overall attractive interaction. It is found that B_q of dilute gas is related to formation of small clusters. A very negative B_q indicates that interactions would be expected to be strongly attractive and predicts aggregation atoms to form clusters. It is concluded that B_q may be used as a predictor of formation of Small Spin-Polarized Tritium (T↓) Clusters.

量子第二维里系数作为小型自旋极化（（T↓）团簇形成的预测因子

量子第二维里系数_Bq已被用作量化T↓原子之间相互作用的平均强度和符号的工具。负的B _q表示总体有吸引力的相互作用。发现稀气体的B _q与小团簇的形成有关。一个非常负的B _q表示相互作用将被认为具有很强的吸引力，并预测聚集原子形成簇。结论是，B _q可以用作小自旋极化ized（T↓）团簇形成的预测因子。
