There is a discrepancy between the fcc-bcc phase boundaries in Xe determined by the two-phase and the lambda-integration methods. To resolve this issue, I performed large scale (4x10(6) atoms) molecular-dynamics simulations of fcc and bcc Xe phases embedded in liquid Xe. Such simulations, which I call N-phase method, allows for the hydrostatic freezing or melting and direct competition of the phases under consideration. As a result of these long (over several nanoseconds) simulations, I can place the triple fcc-bcc-liquid point on the melting curve of Xe between temperatures of 3470 and 4000 K. This suggests that certain effects are not taken into account in the previous work. Possible reasons are discussed.
