On the origin of the anomalous behaviour of 2+ excitation energies in the neutron-rich Cd isotopes

Tomás R. Rodríguez, J. Luis Egido, Andrea Jungclaus

Recent experimental results obtained using $\beta$ decay and isomer spectroscopy indicate an unusual behaviour of the energies of the first excited 2${}^{+}$ states in neutron-rich Cd is…
