摘要：
We measure the specific heat C under pressure of high purity polycrystals of the heavy fermion superconductor U0.978Th0.022Be13 with a pressure resolution equivalent to 0.0002 in Th concentration. We discover a new low temperature phase boundary independent of temperature and close to the critical pressure required to merge the two transitions observed in C(T).
