X-Ray absorption spectrum of the N2+ molecular ion
Abstract: The x-ray absorption spectrum of Nþ2 in the K-edge region has been measured by irradiation of ions stored in a cryogenic radio frequency ion trap with synchrotron radiation. We interpret the experimental results with the help of restricted active space multiconfiguration theory. Spectroscopic constants of the1σ−1u 2Σþu state, and the two 1σ−1u 3σ−1g 1πg2Πu states are determined from the measurements. The charge of the ground state together with spin coupling involving several open shells give rise to double
excitations and configuration mixing, and a complete breakdown of the orbital picture for higher lying core-excited states
