Abstract

The influence of pressure

P

on the superconducting transition temperature

T_{c}

has been determined for the

(U_{1 - x} {Th}_{x}) {Be}_{13}

system. The magnitude of

\frac{d T_{c}}{dP}

increases by a factor of 3 for

x > 1.7 %

where an increase of

T_{c}

is observed at ambient pressure. The phase diagram of

T_{c} (x)

for

P = 10

kbar shows two distinct regions of superconductivity.
