Self-cooling of weak solutions of 3He in 4He during adiabatic melting

Condensed Matter


A new method of pressure regularization in the measuring cell is proposed for experiments on self-cooling of weak solutions. Preliminary results are presented for solutions with concentrations of 2% and 7%. Cooling by a factor of 1.5–2 was observed in the starting-temperature range 40–140 mK.
