We report specific heat, ac/dc magnetic susceptibility as well as static and pulsed field magnetization studies on the distorted kagome magnet Pr3BWO9 down to 0.4~K and up to high magnetic fields. The low-temperature thermodynamic properties are found to be governed by an electronic quasi-doublet ground state; the energy splitting of which amounts to Δ1≃ 18 K and exhibits a quadratic field dependence with geff = 2.6. Fitting of the specific heat data implies that the next excited state is strongly gapped at Δ2=430 K and three-fold degenerate in zero field. Our dc and ac susceptibility studies down to 0.4 K do not detect signatures of distinct spin glass behavior. Pulsed field magnetization measurements up to 60 T confirm the Ising-like paramagnetic nature of the magnetic ground state which is characterized by mJ=± 4 and the anisotropy energy Ea≃ 950 K.
