Angular distribution of binary encounter electrons
- Kansas State Univ., Manhattan, KS (United States); and others
The double differential cross section, DDCS, of the binary encounter electrons (BEe) in 1 MeV/u F{sup q+} + H{sub 2} (q = 4, 6, 8, 9) is measured from 0 to 70 degrees with respect to the beam direction. At 0{degrees} the data confirm the decrease of the cross section with increasing projectile charge state. At larger observation angles, the data are in fair agreement with the prediction proposed by Shingal et al. where the ratio of the DDCS for 6+ ions to bare ions is less than 1 for {theta}{sub lab} > 30{degrees} and greater than 1 for {theta}{sub lab} < 30{degrees} as recently observed for C{sup q+}. We also observed that the energies of the BEe peak are charge state, q, independent at 0{degrees} observation angle, but q dependent at larger observation angles.
