The molar polarizability of3He at low temperatures and its density dependence

Simultaneous capacitance and PVT measurements on liquid and gaseous3He under a variety of temperature and pressure conditions indicate that the molar polarizability of the classical Clausius-Mossotti equation can best be expressed as:α(mole/cm3)=0.123413−0.002376 ρ(g/cm3). Some significant, but often neglected, experimental corrections are discussed.
