THE ENERGIES OF AUTODETACHED STATES OF HYDROGEN NEGATIVE ION AS CALCULATED IN TWO-DIMENSIONAL BASIS * M.Haysak,* M.Dovhanich,** V.Lengyel,** V.Onysko * Institute of Electron Physics, Universitetska st. 21,Uzhgorod 294016, Ukraine ** Uzhgorod State University, Voloshina ST. 32, Uzhgorod 294000, Ukraine A two-dimensional basis have been introduced into the hyperspherical coordinates method which allows to account the contribution of angular and radial correlations into the values of spectroscopic characteristics of two-electron systems. The energies of lower autodetached states of H( have been calculated.
