Polarizabilities of the alkali anions: Li~- to Fr~-

摘要

Static dipole polarizabilities are calculated for the ground states of the alkali anions from Li~- to Fr~-.The polarizabilities include scalar relativistic effects at the second-order Douglas-Kroll level and were computed using the finite-field,coupled-cluster CCSD(T) method with large,carefully optimized basis sets.The relativistic polarizabilities increase with Z,reach a maximum at Cs~-,and then decrease again unlike their nonrelativistic counterparts which increase monotonically with Z.
