Relativistic calculations of the lifetimes and hyperfine structure constants in 67Zn+

Abstract

This work presents accurate ab initio determination of the magnetic dipole (M1) and electric quadrupole (E2) hyperfine structure constants for the ground and a few low-lying excited states in 67Zn+, which is one of the interesting systems in fundamental physics. The coupled-cluster (CC) theory within the relativistic framework has been used here in these calculations. Long-standing demands for a relativistic and highly correlated calculation like CC can be able to resolve the disagreements among the lifetime estimations reported previously for a few low-lying states of Zn+. The roles of different electron correlation effects in the determination of these quantities are discussed and their contributions are presented
