Research output: Contribution to journalArticle


Based on the self-adjoint extension theory mathematically rigorously defined two-body contact interaction in three dimension is reviewed. Local potential realizations of this proper contact interaction are given in terms of Pöschl-Teller, exponential, and square-well potentials. Three-body calculation is carried out for the halo nucleus [Formula Presented] using adequately represented contact interaction.
