    "abstract": "Electron-impact ionization cross sections for the 1s2s 1S and 1s2s 3S\nmetastable states of Li+ are calculated using both perturbative distorted-wave\nand non-perturbative close-coupling methods. Term-resolved distorted-wave\ncalculations are found to be approximately 15% above term-resolved R-matrix\nwith pseudostates calculations. On the other hand, configuration-average\ntime-dependent close-coupling calculations are found to be in excellent\nagreement with the configuration-average R-matrix with pseudostates\ncalculations. The non-perturbative R-matrix and close-coupling calculations\nprovide a benchmark for experimental studies of electron-impact ionization of\nmetastable states along the He isoelectronic sequence.",
