A new determination of the ground state interatomic potential for He2

摘要: A simple accurate potential of the HFD-B form, which appears to be best characterization He-He interaction constructed date, is presented. It has been fitted low temperature second virial coefficient data and recent room viscosity data, while at same time pinning repulsive wall value calculated by Ceperley Partridge 1 Bohr. possesses a well depth 10·948 K, considerably deeper than many empirical or ab initio potentials. reproduces, within experimental error, such dilute gas properties as coefficients, viscosities thermal conductivities over wide range. also predicts, microscopic differential cross sections, high energy integral sections backward glory oscillations in sections. Finally, it accounts for nuclear magnetic relaxation 3He supports weakly bound state 4He interaction.
