**On the phase diagram of superconducting
U _{1-x}Th_{x}Be_{13}**

J. Low Temp. Phys. **86**, 49-56 (1992)

The inelastic scattering of conduction electrons on impurities can stimulate
s-pairing superconductivity and at the same time suppress any non-s-pairing
superconducting state. This may provide an explanation for the nonmonotonic
behavior of the critical temperature T_{c}(x) and thermodynamic and
magnetic properties of the superconducting state in heavy fermionic compound
U_{1-x}Th_{x}Be_{13} resulting from the combination of
two superconducting phases corresponding to trivial and nontrivial
representations of the cubic symmetry group.
