Photodetachment cross sections of the positronium negative ion
The cross sections for the photodetachment from a weakly bound positronium negative ion Ps− below the threshold for the formation of Ps(n = 4) are calculated using the hyperspherical close-coupling method, and are compared with the corresponding spectra for the H− ion. Detailed resonance structures in the spectra near the Ps(n = 2, 3 and 4) thresholds are reported for the first time. The off-re...
متن کاملMass Spectra and Photodetachment of Sodium Fluoride Negative Ion Clusters
A flowing afterglow discharge ion source with NaF vaporized into the flow produces the expected stable anions F-(NaF),, as well as the unusual species Na(NaF); and (NaF); (n < 17). The dominance of (NaF); suggests that it has a particularly stable structure. A fixed-frequency laser has been used to photodetach electrons from mass-selected ion beams extracted from the flowing afterglow. Photoele...
متن کاملDifferential Cross Section Measurements in Ion-molecule Collisions
A 14 m long beam line dedicated to study very small scattering angles in ion-molecule collisions has been set up in the University of Toledo Heavy Ion Accelerator (THIA) Laboratory. Together with position sensitive detectors for both the projectile and the recoil particles’ detection, the beam line can be used to measure the projectile forward scattering angles of up to 2.5 milliradians (mrad) ...
متن کاملResonances in the photodetachment cross section of Au -
This paper reports the observation of autodetaching resonances in photoelectron spectroscopy of Au according to the process Au2 + hv=:> (Aur ) * => Au 2 + e . They appear as sharp features superimposed upon a nearly constant signal associated with direct photodetachment process from Aur :Au + hv=>Au2 + e . By altering the cluster expansion conditions, the dimer anion temperature can be varied. ...
متن کاملResonance structure in the Li- photodetachment cross section.
We report on the first observation of resonance structure in the total cross section for the photodetachment of Li −. The structure arises from the autode-taching decay of doubly excited 1 P o states of Li − that are bound with respect to the 3p state of the Li atom. Calculations have been performed for both Li − and H − to assist in the identification of these resonances. The lowest lying reso...
