| Abstract: | Ab initio calculations have been carried out to study the magnetic dipole and electric quadrupole hyperfine structure constants of 205Pb+. Many-body effects have been considered to all orders using the relativistic coupled-cluster theory in the singles, doubles and partial triples approximation. The trends of these effects are found to be different from atomic systems that have been studied earlier. |
