Scattering states properties of three-body resonantly interacting particles are considered
and are shown to be independent of a form of two-body forces, being determined only presence
of resonances. The resonances produce an effective long range interaction between
three particles [1].
The methods of the quantum theory few-body scattering based on the Faddeev-
Yakubovsky equations [1] in momentum and configuration space are present [2,3] and applied
to the calculation of the dissociative electron attachment to hydrogen and hydrogenhalide
diatomic initial rovibrational exiting molecules H 2 , N 2 , Li 2 , Na 2 , HCl, DCl, HBr,
DBr, HJ, DJ.
The results of this calculations are compered with available experimental data [4] and
other calculation [2-3].
