Abstract
Giant dipole states of singly and excited doubly multielectron atoms in crossed electric and magnetic fields are investigated. A gauge-independent approach to the pseudoseparation of the center of mass yields a generalized multielectron potential in crossed fields that serves as a basis for the study of the dipole states. For doubly excited systems, a class of highly symmetric decentered configurations is found and the properties of the corresponding resonances are determined. An outline on multiply excited systems is given.
