Angular effects in autoionization of 3P doubly excited states in He

The first members of dipole allowed 3Po doubly excited series in helium have been observed in resonant photoexcitation of 1s2s 3Se metastable atoms. A good agreement measured relative photoionization cross sections is achieved when theory includes the radiation damping and, also important, the effec...

Zusammenfassung:The first members of dipole allowed 3Po doubly excited series in helium have been observed in resonant photoexcitation of 1s2s 3Se metastable atoms. A good agreement measured relative photoionization cross sections is achieved when theory includes the radiation damping and, also important, the effects of spin-orbit multiplet splitting on electron angular distribution.
