 [@0000Hah00]. Enriched $^{000}$U targets were bombarded with 00$-$00.0 MeV protons from the Oak Ridge Isochronous Cyclotron forming $^{000}$Np in (p,0n) reactions. Reaction products were implanted on a catcher foil which was periodically rotated in front of a surface barrier Si(Au) detector. Isotopes populated by subsequent $\alpha$ emission were measured. "The $\alpha$-particle energies found for the $^{000}$Pa series are more precise than the previously available values: $^{000}$Pa, 0.00$\pm$0.00 MeV (new value); $^{000}$Ac, 0.00$\pm$0.00 MeV; $^{000}$Fr, 0.00$\pm$0.00 MeV and $^{000}$At, 0.00$\pm$0.00 MeV."
