Abstract:
We evaluate the [Formula Presented]-wave Jost function for the polarization potential and calculate its effective range expansion for [Formula Presented] up to the order [Formula Presented] We investigate not only the phase but also the modulus of the Jost function, generalizing previous works for the expansion up to the order [Formula Presented] of the s-wave phase shift. We discuss the validity domain of this generalized expansion for the interaction of an electron with a Helium atom in any of its three long-lived He states, i.e., [Formula Presented] [Formula Presented] and [Formula Presented] Even though this expansion is shown to be appropriate for most of the applications in electron-atom collisions, we propose here a more precise and simpler approach that provides much better results in a broader energy range when comparing with elaborated ab initio calculations. © 2002 The American Physical Society.
