| Abstract: | We report studies of the negative pressure required to lead to the nucleation of bubbles in superfluid helium-4 in the temperature range down to 0.8 K. At the lowest temperatures studied, the tensile strength is found to be  3 bar. The results are compared with nucleation theory and the possible importance of nucleation on vortices is discussed. |
