Abstract

The pygmy dipole resonance (PDR) of Ni68 was measured by Wieland et al. [Phys. Rev. Lett. 102, 092502 (2009)] through virtual photon scattering and Rossi et al. [Phys. Rev. Lett. 111, 242503 (2013)] through a photoneutron reaction. However, the PDR peaks are observed at different positions: 11 and 9.55(17) MeV respectively. Our calculation based on the deformed relativistic random phase approximation suggests that the discrepancy between these two measurements might be induced by the effect of the shape-coexistence isomeric state in Ni68.
