Abstract
A quadratic diffusion Monte Carlo method has been used to obtain the e quation of state of liquid He-4 including the negative pressure region down to the spinodal point. The atomic interaction used is a revised version of the Aziz potential, which reproduces quite accurately the f eatures of the experimental equation of state. The spinodal pressure h as been calculated and the behavior of the sound velocity around the s pinodal density has been analyzed.
