摘　　要：本文采用改进的排列通道量子力学方法(MACQM),对Li2基态势能曲线进行了计算,结果表明:在核间距R=5·05a0处,能量有极小值-14·88937a·u,由此得到Li2基态结合能为0·0333a·u,所得结果与实验值符合得很好。According to the method of Modified Arrange Channel Quantum Mechanics （MACQM）, the potential curve of the ground state of Li2 is calculated. The result of the calculation shows that the energy curve has a minimal energy-14. 88937a. u at R = 5.05a0 . The binding energy of Li2 （X^1∑g^＋）calculated is 0. 0333a. u. The result agrees well with the experimental result.
