Manifestations of the 2.5-th order phase transition in electronic properties of ω-uranium and cadmium

It is shown that nonlinear temperature dependence of α-uranium superconducting transformation on the pressure P is a result of two-phase transformations of 2.5-th order. By means of parameters characterizing these transformations calculated is the coefficient of temperature expansion being in agreement with the experimental data. Explained is the influence of molybdenum addition on the electronic specific heat and Tsub(k)(p) dependence. Basing on the representation of the 2.5-th order phase transformation analyzed is a nonlinear change of cadmium Tsub(k) in case of uniaxial deformation
