Proton single-particle states have been studied in the isotopes , , and . The reaction () was utilized in the three studies. Additionally, the reaction (, ) was used in the study of levels in . Many new levels were observed and some could be interpreted in terms of single-particle orbitals. Also several assignments previously made on the basis of radioactive decay studies were confirmed by the orbital signatures seen in the proton transfer spectra. Single-particle energies are extracted from the experimental data. Deformations of the nuclear central potential are deduced for and . By use of the parameters of the central field for , the splitting is deduced for mass 250 at zero deformation and estimated for mass 300.
