Abstract
Using an optical interferomertric method, the homogeneous cavitation density of superfluid helium at K is measured and found to be . A well established equation of state for liquid helium at negative pressures converts this to the cavitation pressure bar. This cavitation pressure is consistent with a model taking into account the presence of quantized vortices, but disagrees with previously published experimental values of .
