For both helium isotopes, we have obtained the crossover temperature in the whole range of allowed negative pressures. Our results are compatible with recent experimental results on 4He.4 p.application/pdfeng(c) The American Physical Society, 1996CavitacióHeli líquidTeoria quànticaLiquid heliumCavitationQuantum theoryinfo:eu-repo/semantics/article145732info:eu-repo/semantics/openAccess
