Abstract:
I will outline the resonance scattering theory of electron collisions with diatomic molecules built on "extraction" of the resonance from the continuum using projection operators. Then I will show results for few resonance processes: vibrational excitation of HF, HCl and HBr molecules and dissocitative attachment of electron to the molecules. The last mentioned process is closely related to detachment of an electron from negative ions in collision with atomic hydrogen. I will discuss structures in the collision cross sections and compare with experimental data.
