Description

  • Content Description: Experimental investigations are being carried out into interference effects caused by the coherent population, by electron impact, of autoionizing levels and continua of differing total angular momentum and parity. The work provides information on the atomic excitation and ionization mechanisms by charged particle impact. The experimental technique being used is electron-electron coincidence [or (e, 2e)] spectrometry. Differing binary (I{sup +}) and recoil (I{sup -}) lobe intensities in coplanar (e, 2e) ejected-electron angular distributions may be modeled by interference cross-terms, between opposite parity final-state continua, that change sign when {theta}{sub ej} {r_arrow} {theta}{sub ej} + 180{degrees} in the angular distributions. The magnitude of these cross-terms varies rapidly with ejected-electron energy across overlapping autoionizing resonances. The energy variation in the interference terms may be examined by obtaining the sum (I{sup +} + I{sup -}) and difference (I{sup +} - I{sup -}) between (e, 2e) energy spectra measured at ejected-electron angles 180{degrees} apart. 5 refs., 1 fig.
