How to evaluate model
-The returning electron has a maximal energy of 3.17 Up
-The cross section for ionization is given by an analytic expression which fits e + H(1s) -> e’ + H(2p) and which is an analytic function of Ip, the excitation energy. In this case Ip is a function of R and is the 1sg-2pu energy separation.
- The vibrational wave packet is taken to be a delta function at the classical position of a classical particle moving in the 1sg potential curve.
-The returning electron wave packet spreads according to a transverse velocity imparted to the electron in the initial step.
-At each return, the excitation probability is given by the product of the excitation cross section for the R times the inverse square of the radius of the returning electron wave packet.
-If the D2+ is excited, it immediately goes further into the d+ d+ continuum.
