电阻率、磁化率和比热数据表明UBe13在0.85 K以下具有超导性。正常状态和超导状态下高度反常的低温电子特性导致巨大的电子比热系数γ=1.1J/摩尔K2和相应的磁化率X=1.5×10-2 emu/摩尔。超导态似乎极其稳定，临界场温度导数的初始斜率 (∂H c2/∂T) Tc =-257kOe/K。
Electrical-resistivity, magnetic-susceptibility, and specific-heat data reveal that UBe13 is superconducting below 0.85 K. Highly anomalous low-temperature electronic properties in both the normal and superconducting states result in an enormous electronic specific-heat coefficient γ=1.1J/mole K2 and a corresponding magnetic susceptibility X =1.5×10-2 emu/mole. The superconducting state appears to be extremely stable with an initial slope of the temperature derivative of the critical field(∂H c2/∂T) Tc =-257kOe/K.
