摘要
The temperature dependence of the mobility of a heavy ion in a neutral interacting Fermi liquid is found to be of the form 1=R-ST2ln1T+O(T2) for low T where R and S are constants. The T2lnT term is a consequence of the Friedel density oscillations around the ion and would be absent for the noninteracting Fermi liquid investigated by other authors. The coefficients are calculated for the case of a large hard sphere. The pressure dependence of the coefficients and the predicted temperature dependence are in reasonable agreement with recent experimental data for negative ions in He3. © 1969 The American Physical Society.
