We report magnetoresistance measurements of the heavy electron compound UBe/sub 13/ above the superconducting transition temperature T/sub c/ and below 4 K for pressures P up to 19 kbar and for magnetic fields H up to 9 T. We observe strong negative magnetoresistance at all pressures and temperatures. The resistivity rho is quadratic in temperature T from T/sub c/ up to a maximum temperature of 1 K at 1 bar increasing to 2 K at 19 kbar. The slope of the T/sup 2/ term decreases with both H and with P. We find that delta(H)equivalent-(rho(H)-rho(0))/rho(0) for a given pressure scales as a function of H/T and exhibits power-law behavior over one decade with an exponent of 1.7. In addition, delta(H) at high pressure shows this same power law over a more limited H/T range.
