چکیده

The Auger rates of triply excited Rydberg series are shown to behave rather differently from doubly excited series. It is shown that in hollow atoms the Auger decay rates for Rydberg series of the type 2l2l(')nl(") with n>/=2 are expected to be nearly independent of n, while for doubly excited series of the type 2lnl(') the decay rate in general decreases with increasing n. In addition the ratio between the rates for 2l2l(')nl(") Rydberg series with different l(") values will be fixed and often the ratio will be equal to one.

Hyperspherical analysis of doubly and triply excited states of Li

A computational method for calculating the hyperspherical adiabatic potential curves for three-electron atomic systems is presented. This method allows us to obtain accurate potential curves for any symmetries more efficiently. The potential curves for the Li(S) symmetry are analyzed. For the ground state, the energy calculated using the single channel adiabatic approximation is in good agreeme...

Angle-resolved photoelectron spectrometry studies of the autoionization of the 2s(2)2p 2P triply excited state of atomic lithium: experimental results and R-matrix calculations

We have measured the angle-resolved energy dependence of the electrons emitted over the energy range of the triply excited 2s(2)2p 2P lithium resonance using synchrotron radiation. We have also calculated the behavior of the angular distribution parameter beta using the R-matrix approximation. Experimental and theoretical results are in good agreement and show deep minima in the 1s2p (1, 3)P io...

Destruction of quantum coherence and stochastic ionization of Rydberg electrons by fluctuating laser fields.

It is shown that diffusion and stochastic ionization of an optically excited Rydberg electron are generic long time phenomena which are consequences of the destruction of quantum coherence by laser fluctuations. Quantitatively these novel fluctuation-induced phenomena are characterized by non-exponential time evolutions whose power law dependences can be determined analytically. It is demonstra...

Influence of the helium autoionization structures on the single/double ionization signal

Calculations of intense field (around 10 W/cm) singleand double-ionization processes in helium at XUV wavelengths are presented. The laser wavelength is chosen near the |2s2p P〉 autoionization structure and the dynamics are explored. Single and double ionization yields, as well as the photoelectron energy spectrum for photon energies around the autoionization structure are calculated. In the ca...

Laser-induced fluorescence studies of HfF+ produced by autoionization.

Autoionization of Rydberg states of HfF, prepared using the optical-optical double resonance technique, holds promise to create HfF(+) in a particular Zeeman level of a rovibronic state for an electron electric dipole moment search. We characterize a vibronic band of Rydberg HfF at 54 cm(-1) above the lowest ionization threshold and directly probe the state of the ions formed from this vibronic...
