Abstract
Heat capacity measurements with significantly improved resolution find the presence of a peak in a solid He4 sample in coexistence with liquid. With improved crystallinity, the peak decreases in height and moves to lower temperature. A hysteretic heat capacity signature consistent with He3-He4 phase separation, not detected in an earlier work is clearly observed.
