Abstract
We trace the evolution of the shape of the two-electron photoionization spectrum with photon energy growth using quite a precise two-electron wave function, obtained by the correlation function hyperspherical harmonic method. We obtain the values of {omega}{sub 1} and {omega}{sub 2} at which the spectrum curve changes its shape. At {omega}={omega}{sub 1} the U shape changes to a W shape. At {omega}={omega}{sub 2} the central W peak splits into two. We consider ground states of the helium atom and of heliumlike ions with the nuclear charge Z, the negative ion of hydrogen H{sup -}, and the excited n{sup 1}S state of helium. The limiting laws for Z>>1 and n>>1 are obtained. The analysis is carried out without calculations of the particular energy distributions themselves.
