Decay of on-line mass-separated ${}_{}{}^{133}{}_{}{}^{}\mathrm{Pr}$ sources were carried out. γ, x-ray, conversion-electron singles and time-multiscale, and γ-γ-t and ${\mathit{e}}^{\mathrm{-}}$-γ-t measurements were used to deduce the ${}_{}{}^{133}{}_{}{}^{}\mathrm{Pr}$ decay scheme with 20 levels up to 1881 keV. The low-energy excitation structure of ${}_{}{}^{133}{}_{}{}^{}\mathrm{Ce}$ is compared with predications of interacting boson-fermion model calculations.
