摘要：

We compare the properties of vacancies in He-4 implied by X-ray, NMR, and acoustic measurements with specific heat, pressure, and melting curve data. Taken together, these different measurements indicate that the model of vacancies as occupying a narrow band of states cannot be correct. Better agreement can be obtained by assuming that vacancies occupy, a wide band but inconsistencies remain. An unambiguous determination of the properties of vacancies requires additional experimental and theoretical work.
