The full quantal molecular orbital close-coupling(QMOCC)[1] method and optical potential[2] method have been investigated to study the nonradiative charge transfer processes and radiative decay processes for Li-colliding with H atoms.It is found that rich resonance structures appear in the cross sections of these processes in the energy range of 0.1 – 1.5 eV.The primary resonances are identified and studied by QMOCC(by fitting the eigenphase sum of the K-matrix)and complex absorbing potential(CAP)method.Noted that the eigenphase sum jump by π near the resonance position.For the energy region of 1.0-1.4eV,pronounced resonance positions Er and resonance widths Γ of resonant states in the A2 ∑+potential are given in Table 1.and the resonance parameters calculated by CAP agree very well with those extracted from QMOCC calculations.Fig.1 presents a case of these resonance parameters.
