9Be NMR spectra have been studied in the heavy-fermion compound UBe13 as functions of spectrometer frequency, crystal orientation, and temperature. BeI-site isotropic Knight shift and BeII-site anisotropic shifts, corresponding hyperfine fields, and quadrupolar tensors have been determined. For T {less-than or approximate} 10 K a typical heavy-fermion Knight shift anomaly is observed. © 1987.
