Charged Snowball in Non-Polar Liquid

Original · EN

The problem of correct definition of the charge carrier effective mass in superfluid helium is revised. It is demonstrated that the effective mass M of a such quasiparticle can be introduced without use of the Atkins's idea concerning the solidification of liquid He in the close vicinity of ion. The two-liquid scenario of the ''snowball'' mass formation is proposed. The normal fluid contribution to the total snowball effective mass, the physical reasons of its singularity and the way of corresponding regularization procedure are discussed. Agreement of the theory with the available experimental data is found in the wide range of temperatures.
