Schlagheck, Peter and Pingel, Detlef and Schmelcher, Peter (2003) Collinear helium under periodic driving: Stabilization of the asymmetric stretch orbit. Physical Review A 68, 053410.
The collinear eZe configuration of helium, with the electrons on opposite sides of the nucleus, is studied in the presence of an external electromagnetic (laser or microwave) field. We show that the classically unstable \"asymmetric stretch\" orbit, on which doubly excited intrashell states of helium with maximum interelectronic angle are anchored, can be stabilized by means of a resonant driving ...
