Angular correlation of outgoing electrons following ionization of H₂and N₂by electron impact

Direct experimental measurement of electron impact ionization‐excitation branching ratios: 2. Angular distribution of secondary electrons from N2 at 100 eV

“…Comparison of these data with those in Figure 3 shows that the X state distribution appears more intense relative to the A state distribution than in the Figure 3 data. This is expected since the peak intensity is shown here, rather than the area, and of the cases studied by Jung et al [1975]. In summary, the two previous experiments are consistent with our work, although they are not directly comparable.…”

Triply differential (e,2e) cross sections for ionization of the nitrogen molecule at large energy transfer

“…A large body of theoretical and experimental works have been reported for EMS studies of molecular targets, see, e.g. [2,4] and references therein, whereas studies concerned with the dynamics of the ionization process of molecules are less numerous [5][6][7][8][9][10][11][12], mainly due to the difficulty in developing a realistic theoretical model to describe this process. However, there has recently been a renewed interest in such dynamics studies, both experimentally [13,14] and theoretically [15][16][17][18][19][20][21].…”

Triply differential study of positron-impact ionization of H2

“…In this paper, we compare our TDCS for positronimpact ionization of molecular hydrogen with the electron theoretical data of Stia et al [9] and with the electron experimental data of Jung et al [4] and Cherid et al [5]. In all cases, the studied arrangements correspond to coplanar asymmetric collisions.…”

“…The fact that our positron-impact TDCS in the binary peak are [9] by the dashed curve. The relative experimental data of [4] for electron-impact ionization are represented by the triangles with error-bars. The experimental data was normalized to fit the MBBK binary peak values of [9].…”

“…These measurements focused on the electron capture to the continuum (ECC) phenomenon, which occurs when both the scattered positron and the ejected electron move in the forward direction. For the electron-impact the experimental TDCS exist for a large number of energies and angles [4,5].…”
