Evidence for a positive parity decoupled band in neutron-deficientCd103

Abstract

Excited levels of ${}_{}{}^{103}{}_{}{}^{}\mathrm{Cd}$ have been investigated in the ${}_{}{}^{94}{}_{}{}^{}\mathrm{Mo}({}_{}{}^{12}{}_{}{}^{}\mathrm{C}, 3n\gamma ){}_{}{}^{103}{}_{}{}^{}\mathrm{Cd}$ reaction and observed up to 4027 keV excitation energy. A decoupled band, based on the 188.1 keV $\frac{7}{2^{+}}$ intrinsic state has been observed up to spin $\frac{19}{2^{+}}$. An interpretation of the experimental results is proposed in the framework of the axial symmetric rotor plus particle model using deformed self-consistent quasiparticle states.
