A.2009-10-292009-10-2919930163-1829https://hdl.handle.net/2445/9864We have investigated the nucleation rate at which cavities are formed in 4He and 3He at negative pressures due to thermal fluctuations. To this end, we have used a density functional that reproduces the He liquid-gas interface along the coexistence line. The inclusion of thermal effects in the calculation of the barrier against nucleation results in a sizable decrease of the absolute value of the tensile strength above 1.5 K.4 p.application/pdfeng(c) The American Physical Society, 1993CavitacióHeli líquidTemperatures baixesFluctuacions (Física)CavitationLiquid heliumLow temperaturesFluctuations (Physics)Thermal nucleation of cavities in liquid helium at negative pressuresinfo:eu-repo/semantics/article76014info:eu-repo/semantics/openAccess
