The yield of resonances in the He(e, 2e)He+ reaction depending on the ejection angle

In the first Born approximation the interference and relation of the yields of overlapping 1P and 1D autoionization states (AIS) in the He(e,2e)He+ reaction in the dependence on the ejection angle in a wide region of kinematic variables are considered. It is shown that in the quasi-elastic peak region there exists a region of ejection angles for which at certain kinematic situations the resonance contributions of the 1P and 1D AIS lead to the complicated asymmetric structure in the spectrum triple differential oscillator strengths. In the recoil peak these resonances, as a rule, are fairly isolated and the relation of their yields varies noticeably depending on kinetic variables. 17 refs.; 7 figs.; 1 tab
