The elastic and excitation processes for 
systems are investigated in this article. The calculations are performed within the framework of R-matrix theory implemented using the pseudo-state formalism. Electron attachment to 
during electron collision is found to produce temporary negative ion states. We observed two negative ion states, 
and 
, in the elastic scattering channel for the present targets. The generation of negative ions in the inelastic (electronic excitation) channel is also observed. Formation of 
ion is traced out by investigating the dissociative electron attachment process for the scattering system. A detailed investigation of the elastic and electronic excitation processes of systems is reported here. The results presented here will be key to understand various intermediate processes occurring in - and HCO-rich environments.
