The method of time-resolved XUV photoelectron spectroscopy is applied in a pump–probe experiment on a liquid micro-jet. We investigate how the XUV energy spectra of photoelectrons are influenced by the space charge created due to ionization of the

We report on strong-field ionization of dense water gas in a short infrared laser pulse. By employing a unique combination of photoelectron spectroscopy with a liquid micro-jet technique, we observe how the character of electron emission at high kine

Strong-field ionization of dense molecular gases in a short infrared laser pulse is studied by means of photoelectron spectroscopy combined with a liquid microjet technique. By increasing the gas density, we observe how the laser- assisted electron s

Twelve previously unobserved Feshbach resonances associated with the autodetaching decay of doubly excited states of He{sup {minus}} have been observed in the process of photodetachment. Seven resonant states of {sup 4}P symmetry and one of {sup 4}S

The photodetachment cross section of He^- has been measured in the photon energy range 2.9 eV to 3.3 eV in order to investigate doubly excited states. Measurements were made channel specific by selectively detecting the residual He atoms left in a pa

The energies of the As− fine structure components 4p43P1 and 4p43P0 have been determined relative to the 4p43P2 ground state by using photodetachment electron spectroscopy. Fine structure splittings of ΔE(3P1 − 3P2) = 125(3) meV and ΔE(3P0 −

Measurements of the photodetachment cross section of have been performed in the vicinity of the threshold, with photon energies ranging from 5.23 - 6.04 eV. The experimental cross section is nearly constant throughout this energy region, in marked co

We report on the first experimental observation of a new threshold behavior observed in the $5\text{ }^{2}G$ partial channel in photodetachment of ${\mathrm{K}}^{\ensuremath{-}}$. It arises from the repulsive polarization interaction between the deta

We present experimental and theoretical results on photodetachment of ${\mathrm{Br}}^{\ensuremath{-}}$ and ${\mathrm{F}}^{\ensuremath{-}}$ in a strong infrared laser field. The observed photoelectron spectra of ${\mathrm{Br}}^{\ensuremath{-}}$ exhibi
