本文研究了三维Salpeter哈密顿量H = β(m2 + p2)1/2 + vr 2,v>0,β>0的特征值nl.通过几何论证,我们证明了对于适当的P值,简单的半经典公式nl min r>0{v(Pnl/r)2 + β(m2 + r2)1/2}给出了问题所有本征值的能量上界和下界.
We study the eigenvalues nl of the Salpeter Hamiltonian H = β(m2 + p2)1/2 + vr2, v>0, β>0, in three dimensions. By using geometrical arguments we show that, for suitable values of P, here provided, the simple semiclassical formula nl≈min r>0{v(Pnl/r)2 + β(m2 + r2)1/2} provides both upper and lower energy bounds for all the eigenvalues of the problem.
