Effect of dipole moment on the collision induced dissociation of HD⁺ion by electron impact

The effects of the dipole moment of HD + ion on the differential and total cross section for the collision induced dissociation of HD + ion by electron impact have been analysed quantitatively. For this purpose the Born-Oppenheimer approximation has been used and the electron-dipole interaction term has been included in the hamiltonian for exchange scattering amplitude. Some very interesting features in the differential and total cross sections for dissociation have been predicted which are due to the heteronuclearity and the dipole moment of the molecular ion.
