[Display omitted] •The quantum second virial coefficient Bq has been calculated from first principles.•Bq quantifies the average magnitude and sign of interactions between T↓ atoms.•The main achievement of this work is the prediction of formation of T↓ clusters. The quantum second virial coefficient Bq has been used as a tool to quantify the average magnitude and sign of interactions between T↓ atoms. A negative Bq represents an overall attractive interaction. It is found that Bq of dilute gas is related to formation of small clusters. A very negative Bq indicates that interactions would be expected to be strongly attractive and predicts aggregation atoms to form clusters. It is concluded that Bq may be used as a predictor of formation of small spin-polarized tritium (T↓) clusters.
