Recent developments and new trends in (e,2e) and (e,3e) studies

Abstract

The latest, most imponant developments in (e, 2e) studies are reviewed from an metric energy sharing collisions involving double scattering mechanisms, core states ioniratian, (e, 2e) measurements for autoionizing states and for the simultaneous excitation and ionization r.f the target. Double ionizing processes with coincidence detection of two or three elec.rans in the final slate are also reviewed, including (e, &Auger) experiments and the new born ( e , ( 3 -l ) e ) and ( e , 3 e ) domain.

Three-dimensional imaging of atomic four-body processes

“…The characteristic double lobe structure with peaks at (θ e = 90 o , ϕ e = 0 o ) and (θ e = 90 o , ϕ e = 180 o ) well-known from high-energy electron-impact studies in the scattering plane [1][2][3] is clearly observable. The (θ e = 90 o , ϕ e = 180 o ) -maximum (dubbed the binary peak), which occurs in the direction of q, is relatively easy to understand.…”

Dynamical (e,2e) studies of tetrahydrofurfuryl alcohol

“…Electronic mail: michael.brunger@flinders.edu.au. ular targets 6 as well as to reveal details about the bound electronic structure of the target. In the latter case, the kinematics are usually known as electron momentum spectroscopy.…”

The (e,2e) spectroscopy, achievements and perspectives

“…A good fraction of the capability of the TDCS to discriminate between different models, even when they reproduce the shape of the measured distribution, comes from the knowledge of the absolute cross section. Various different experimental methods have been developed over the years (32). Most of the TDCS are brought to the absolute scale by normalisation procedures, based on the assumption that the double or triple generalised oscillator strength (GOS) converges to the optical limit at vanishing momentum transfer (Lassettre theorem).…”
