Description
It is demonstrated that weak boron doping of UBe13 drastically alters the temperature dependence of the specific heat just above and also below the superconducting transition. A strong enhancement of the anomaly at Tc and distinct deviations from mean-field behavior are the most significant features. The influence of small amounts of boron replacing Be in thorium-doped UBe13 is shown to depend on the concentration of Th impurities. Excessive specific heat well below Tc in these compounds indicates considerable variation of the electronic spectrum even at very low temperatures
