【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。更多还原

【Abstract】 According to the method of Modified Arrange Channel Quantum Mechanics （MACQM）, the potential curve of the ground state of Li₂ is calculated. The re sult of the calculation shows that the energy curve has a minimal energy -14.8 8 937a.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 .更多还原
