Selectively excited X-ray emission spectra of N2

Resonant soft X‐ray emission and X‐ray absorption studies on Ga1‐xMnxN grown by pulsed laser deposition

“…For the spectra recorded at resonance with the N 2 π* peaks, at 401 and 401.50 eV, the N K RXES spectrum is a mix of GaN fluorescence with a narrow N 2 fluorescence spectral feature dominating at 393 eV which is attributed to the 3σ g bonding orbital of N 2 [7]. In addition, the elastic peak excited at the second vibrational level shows inelastic scattering behaviour similar to that previously noted in molecular N 2 [7].…”

On the production of N+2ions at the N 1s edge of the nitrogen molecule

“…At the N 1s → 3pπ excitation, a small part of x-ray fluorescence intensity goes to the 2σ −1 u 3pπ 1 u state, which, as judged by the transition energy, should be located above the IP and could thus be followed by autoionization to the ground state of N + 2 . The soft x-ray emission energies are expected to remain practically constant at higher core-to-Rydberg excitations because the N 1s → 3pπ soft x-ray emission spectrum is shifted from the non-resonant spectrum, resulting from the (N 1s) −1 states, by only 0.05 eV [26]. This means that the initial and final states of soft x-ray emission should increase by the same amount, when the higher core-to-Rydberg resonances are excited.…”

Soft X‐Ray Absorption and Emission Spectroscopy in the Studies of Nanomaterials

“…The SXES spectrum of the N 2 molecule is less complex; thus the symmetry restriction and parity conservation effects are seen more clearly in this case [62]. One can always (without antisymmetric vibronic coupling) superpose localized core holes so that the superposed wave function keeps (ungerade or gerade) symmetry.…”
