Relativistic manybody calculations of electricdipole matrix elements, lifetimes, and polarizabilities in rubidium
Abstract
Electricdipole matrix elements for nsn'p, ndn'p, and 6d4f transitions in Rb are calculated using a relativistic allorder method. A thirdorder calculation is also carried out for these matrix elements to evaluate the importance of the highorder manybody perturbation theory contributions. The allorder matrix elements are used to evaluate lifetimes of ns and np levels with n=6,7,8 and nd levels with n=4,5,6 for comparison with experiment and to provide benchmark values for these lifetimes. The dynamic polarizabilities are calculated for ns states of rubidium. The resulting lifetime and polarizability values are compared with available theory and experiment.
