This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant new evidence is presented for resonant-transfer-and-excitation (RTE) in ion-atom collisions. This process occurs when a target electron is captured simultaneously with the excitation of the projectile followed by deexcitation via photon emission. RTE, which is analogous to dielectronic recombination (DR), proceeds via the inverse of an Auger transition, and is expected to be resonant for projectile velocities corresponding to the energy of the ejected electron in the Auger process. RTE was investigated by measuring cross sections for projectile K x-ray emission coincident with single electron capture for 15 to 200 MeV 16S/sup 13 +/, 100 to 360 MeV 20Ca/sup 16 +/ /sup 17 +/ /sup 18 +/ and 180 to 460 MeV 23V/sup 19 +/ /sup 20 +/ /sup 21 +/ ions colliding with helium. Strong resonant behavior, in agreement with theoretical calculations of RTE, was observed in the coincidence cross sections.

Book excerpt: Significant new evidence is presented for resonant-transfer-and-excitation (RTE) in ion-atom collisions. This process occurs when a target electron is captured simultaneously with excitation of the projectile followed by deexcitation via photon emission. RTE, which is analogous to dielectronic recombination (DR), proceeds via an inverse Auger transition, and is expected to be resonant for projectile velocities corresponding to the energy of the ejected electron in the Auger process. Cross sections for projectile K x-ray emission coincident with single electron capture have been measured for 70 to 160 MeV 16S/sup 13 +/, 100 to 360 MeV 20Ca/sup 16 +/ /sup 17 +/ /sup 18 +/ and 180 to 460 MeV 23V/sup 19 +/ /sup 20 +/ /sup 21 +/ ions colliding with helium. Strong resonant behavior, in agreement with theoretical calculations of RTE, is observed as a function of beam energy in the measured cross sections. For Ca and V ions two maxima are observed in the energy dependence of the measured coincidence cross sections. Theoretical calculations show that these maxima are correlated to two groups of intermediate resonant states in the RTE process for which the excited and captured electrons occupy levels with principal quantum numbers n = 2,2 and n = 2, greater than or equal to 3. 13 references, 6 figures.

Available in PDF, EPUB and Kindle. Book excerpt: Coincidence measurements of charge transfer and simultaneous projectile electron excitation provide insight into correlated two-electron processes in energetic ion-atom collisions. Projectile excitation and electron capture can occur simultaneously in a collision of a highly charged ion with a target atom; this process is called resonant transfer and excitation (RTE). The intermediate excited state which is thus formed can subsequently decay by photon emission or by Auger-electron emission. Results are shown for RTE in both the K shell of Ca ions and the L shell of Nb ions, for simultaneous projectile electron loss and excitation, and for the effect of RTE on electron capture.
