The Scenario....
The 2l2l’2l’’ triply excited states of F9+ had recently
been observed in fast energy collisions using the
method of triple ion capture to a bare ion using the
paracentric HDA [Zamkov. et all, Phys. Rev. A, 67, (050703), 2003]
Since these states are not completely described within
the IPM, C.D. Lin et all were working on new ways
to describe these states from the correlated  motion of
the electrons within the state. [Phys.Rev. A, 67, 022511]
