Pressure dependence of the specific-heat jump at the superfluid transition and the effective mass of 3He
- 1. Low Temperature Laboratory, Helsinki University of Technology, SF-02150 Espoo 15, Finland
Description
The specific heat of liquid 3He has been measured from 1 to 10 mK between 0 and 32.5 bars. The values implied for the effective mass are considerably smaller than the currently accepted ones. Near zero pressure the specific-heat jump is close to the BCS value 1.43, and at 32.5 bars it has reached 1.90 in the B phase and 2.04 in the A phase. The temperature dependence of the specific heat in the B phase agrees with a model of Serene and Rainer. The latent heat at the A-B transition has been measured
