Description
We use the non-relativistic R-matrix method to treat ultralow-energy electron scattering from the alkaline-earth atoms Mg, Ca, and Sr. The sensitivity of the predictions for the scattering length is analysed by comparing results obtained from a variety of structure and collision models. We estimate the electron scattering lengths to be -2.5a0 for e--Mg, -12a0 for e--Ca, and -18a0 for e--Sr, respectively. (letter to the editor)
