The linear magnetostriction ({lambda}) and the coefficient of linear thermal expansion ({alpha}) of a single-crystalline sample of the heavy-fermion compound UBe{sub 13} have been determined for elongation directions along and perpendicular to the applied magnetic field ({bold B}{parallel}(100)), in the temperature interval 0.3{lt}{ital T}{lt}12 K and for fields {ital B}{lt}8 T. We find neither evidence for antiferromagnetic order ({ital T}{sub {ital N}}=8.8 K), nor for magnetostrictive oscillations, which were reported recently by Kleiman {ital et} {ital al}. (Phys. Rev. Lett. 64, 1975 (1990)). Instead {lambda} varies proportional to {ital B}{sup 2} as expected for a normal paramagnetic metal. The low-temperature normal-state electronic Grueneisen parameter is unusually large and drops rapidly in the superconducting phase ({ital T}{sub {ital c}}=0.85 K). We also report magnetostriction measurements on UBe{sub 13} below {ital T}{sub {ital c}}. The magnetovolume effects in the superconducting phase are strongly anisotropic and reveal a large hysteresis.
