The excitations of ions in plasmas are mainly caused by the electron impact. When plasma density 
is low, this process described well by the isolated scattering of electrons. As the density increases, 
simultaneous scattering of many electrons becomes important. In the present study, we formulate the 
excitation of the 1s - 2s transition for hydrogenic ions by the simultaneous two-electron scattering 
in terms of hyperspherical coordinates. We derived analytical formulas with respect to the matrix 
elements in the first Born approximation, and compare with the numerical integrations. In the hyper-
spherical coordinates, we can treat the problem of simultaneous multi-body scattering as a problem of 
one-body potential-scattering in the multi-dimensional space. We use unperturbed wave functions for 
the target electron.},
