Dipole polarizabilities of plasma-embedded Ps− and H− ions. Physics Letters A. 372:4253-4256., Number 23
AbstractWe have investigated the effect of weakly coupled hot plasmas on the dipole polarizabilities of positronium negative ion and hydrogen negative ion. The plasma effect is taken care of by employing a screened Coulomb (Yukawa) potential of Debye type, and highly correlated exponential wave functions are used. Dipole polarizabilities for various screening parameters are reported.

Bound states and dipole polarizability of hydrogen molecular ion H+2 in weakly coupled hot plasmas. Physics Letters A. 368:476-479., Number 6
AbstractThe effects of hot-dense plasmas on the bound states and the dipole polarizability of the ground state of Coulomb three-body molecular ion H+2 have been investigated using highly correlated basis functions and by considering the Debye shielding approach of plasma modeling. The ground S state and the first excited P state energies along with the dipole polarizability for different shielding parameters are reported.
