Coulomb excitation studies in antimony isotopes

Various low-lying energy levels up to 1.145 MeV in ${}_{}{}^{121}{}_{}{}^{}$,123Sb have been Coulomb excited using 3.0–4.0 MeV proton-beam energies. The reduced transition probabilities of the excited levels have been newly deduced from the measured yields of the deexcitation gamma rays. The values of mixing ratios for a few transitions and the removal of ambiguities in the spin values of some levels have been presented from the angular distribution analysis.
