We present magnetic field-temperature ({ital H}-{ital T}) phase diagrams of the double transitions of superconducting U{sub 1{minus}{ital x}}Th{sub {ital x}}Be{sub 13} with {ital x}=0.030 and {ital x}=0.022. For both samples increasing the applied magnetic field moves the two transitions to lower temperature while decreasing their separation in temperature. For the {ital x}=0.030 sample, the transitions remain distinct for {ital T}{approx_gt}100 mK. For {ital x}=0.022, however, the two transitions appear to merge near {ital H}=20 kOe and {ital T}=350 mK, analogous to the situation in the related heavy fermion superconductor UPt{sub 3}. {copyright} {ital 1996 The American Physical Society.}
