چکیده
Articles you may be interested in Single-photon and resonance-enhanced multiphoton threshold ionization of the allyl radical Single-photon threshold photoionization spectra for jet-cooled NO have been measured for the v+ =0 and 1 vibrational levels of the X I~+ ground state of NO+. The NO+ rotational state distribution for the v+ =0 level is shown to be perturbed by nearby autoionizing levels, whereas the v+ = 1 level exhibits a cation rotational distribution which is in near quantitative agreement with calculated spectra near threshold. Only small changes in total angular momentum are observed (ILlJI = I J+-J" I <;5/2) even though a wide range of photoelectron angular momenta (1=0-3) are predicted to contribute to the near-threshold photoelectron continua. The present results are also discussed in light of recently published two-photon threshold photoionization spectra of NO which exhibit nearly identical NO+ rotational state distributions.

A New Scaling Law for Double-photoionization Processes
We have measured the double-to-single photoionization ratio of atomic lithium and beryllium using the ion time-of-flight method. The photon beam of the PGM undulator beam line ionizes the vaporized target atoms. The ions created are extracted by a pulsed electric field across the interaction region and are detected by a Z-stack of micro-channel plates [1]. In the figure shown above, we compare ...
متن کاملDouble K -shell photoionization and hypersatellite x-ray transitions of 12 Z 23 atoms
Single-photon double K-shell ionization of low-Z neutral atoms in the range 12 Z 23 is investigated. The experimental method was based on measurements of the high-resolution Kα hypersatellite x-ray spectra following the radiative decay of the K-shell double-vacancy states excited by monochromatic synchrotron radiation. The photon energy dependence of the double K-shell ionization was measured o...
متن کاملPhotoionization of helium above the n = 2 photoionization threshold
2014 Using the technique of electron spectrometry and the synchrotron radiation of the storage ring ACO, the photoionization of helium has been investigated between 69 and 150 eV. The probability to leave the residual ion in the n = 2 excited state has been measured as a function of photon energy. The absolute partial photoionization cross section for this process has been determined and found ...

متن کاملSingle-photon and resonance-enhanced multiphoton threshold ionization of the allyl radical.
Pulsed-field-ionization zero-kinetic-energy photoelectron spectra of jet-cooled allyl radical (C(3)H(5)) have been recorded following single-photon and resonant multiphoton excitation. Simulations based on an orbital ionization model and rovibronic photoionization selection rules reliably describe the observed intensity distributions in the photoelectron spectra obtained from single-photon exci...
