文摘The ground state and three low-lying states of the H_(3)^(+)are determined by SOCI(Second Order Configuration Interaction)calculations.The results indicate that the^(3)Σ_(u)^(+)state of H_(3)^(+)3 is a bound state,but^(1)A_(1)and^(3)A_(1)states are not stable,each of them will dissociate into H_(2)^(+)and H atom.The SOCI energy-1.1144065au at an equidistant nuclear separation of 1.296A is in good agreement with the lowest value reported so far.
