Abstract:
We present in this communication the results of our calculation of triple differential cross section (TDCS) and spin asymmetry in TDCS in (e, 2e) processes on Li, Be+, B+2 and C+3 targets at an incident electron energy 49 eV above the ionization potential for equal as well as unequal energy sharing conditions. We have performed the calculation in distorted wave Born approximation (DWBA) formalism using static exchange potential. We also present our calculation of spin asymmetry for Li like targets as a function of energy sharing ratio and compare it with the available experimental data for Li atom. We discuss the role of exchange effect in producing spin asymmetry. We observe that the triplet scattering process plays an important role as the nuclear charge is increased. Further we observe that the spin asymmetry variation with the energy sharing ratio is also sensitive to the nuclear charge
