“…20 The interpretation offered by those workers is in agreement with that suggested here, and is validated by the clear delineation of several members of each series. Their estimates of the LJJJ-and Ljj-term energies agree with the estimates obtained above the K-series data within 0.1-0.2 eV.…”

The relative positions of the principal features of the emission and absorption spectra of argon in its K series have been measured. The energy difference between the If-series Rydberg limit and the peak of K(3 t 3 is compared with the optical ionization potential. Location of the If-series limit via the experimental ionization potential leads to new values for the I/JJ and Lj-rj terms from measurements of Ka 2 and Ka t . These are in reasonable agreement with Hartree-Fock calculations, and with recent grating measurements from other laboratories and single-crystal measurements newly reported here.

Auger effect in the presence of strong x-ray pulses

We study the role of propagation of strong x-ray free-electron laser pulses on the Auger effect. When the system is exposed to a strong x-ray pulse the stimulated emission starts to compete with the Auger decay. As an illustration we present numerical results for Ar gas with the frequency of the incident x-ray pulse tuned in the 2p 3/2 -4s resonance. It is shown that the pulse propagation is accompanied by two channels of amplified spontaneous emission, 4s-2p 3/2 and 3s-2p 3/2 , which reshape the pulse when the system is inverted. The population inversion is quenched for longer propagation distances where lasing without inversion enhances the Stokes component. The results of simulations show that the propagation of the strong x-ray pulses affect intensively the Auger branching ratio.

“…Of particular interest are hydrides built with second row elements like HCI, H2S, PHa and Sill 4 which shows very rich 2p photoabsorption spectra [1][2][3][4][5] in contrast with the argon spectrum [6,7]. In this isoelectronic series, there is a continuous change from valence to Rydberg type of orbitals [8,93.…”

High resolution photoabsorption spectra of HC1 and C12 have been measured near the chlorine K edge in the 2810-2850eV photon energy range. Below the C1 K edge, the strongest resonance is interpreted as a simple core excitation into the unoccupied a* valence orbital for both molecules, leading to a markedly repulsive state. Higher resonances due to low lying Rydberg states, are observed in both systems, but with a larger oscillator strength for HC1 as compared to C12. In C12, the o-* orbital is deep enough to avoid any mixing with Rydberg orbitals. In HC1, we observe the dipole forbidden C1 ls--,4s transition which denotes a strong 4s-4p hybridization. Above the C1 K edge, the multiplet features seen for HC1 are analysed in terms of doublecore-valence excited vacancy states. In Ct2, their counterpart are found very close to the ionization threshold because of the deep a* orbital and possibly because the excited core and valence electrons originates either from the same atomic site or from different ones.
