摘要：

The electrical conductivity of noble gas plasmas is investigated by using the relaxation-time approximation in the density range 10(-5)-10 g cm(-3) and temperature range 10(4)-10(5) K. The electrical conductivity calculated shows reasonable consistency with shock wave experiments and theoretical simulations at above 2x10(4) K where the Coulomb interaction dominates. A nonmetal to metal transition in helium plasma is predicted at 2.4 gcm(-3) and shown reasonable agreement with the most recent shock wave experiment (above 1.9 gcm(-3)). Furthermore, the insulator-metal transition densities of all the noble gas plasmas are predicted and compared with available results. (C) 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
