Temperature effects on the perturber induced shift of dopant ionization energies in He and Ne
In this Letter, temperature effects on the perturber induced shift Delta D(rho(P)) [rho(P) = perturber number density] of the dopant ionization energy in the repulsive gases Ne and He are investigated at low to medium perturber number densities (i.e., rho(P) <= 6.0 x 10(21) cm(-3)). We show that these effects arise from changes in the ensemble averaged dopant/perturber polarization energy rather than from changes in the energy of the quasi-free electron. (C) 2011 Elsevier B.V.
