【 摘 要 】

Previously, a two-component pseudopotential "shelf Coulomb" plasma model has been developed. A Monte-Carlo study of canonical NVT ensemble with periodic boundary conditions has been performed to find gas-liquid critical point in the model. In present work additional calculations have been carried out using hybrid Gibbs statistical ensemble Monte- Carlo technique. New data for 15kT shelf has been obtained and presented in this paper. More accurate simulations confirmed the melting curve position and triple point estimations of the model (T∗ ≈ 0.0476, ν∗ ≈ 6 × 10-4).
