The properties of vacancies in solid ⁴He as studied by pressure measurements
The temperature dependence of the pressure at a constant volume in solid ⁴He in the low-density hcp phase has been measured. The measurements are analyzed in terms of a localized vacancy model and the free Bose gas model of vacancies in solid helium. The results agree better with the free Bose gas m...
