摘要：Based on the nonlinear Lie algebra, a new framework is put forward to treat the problem of angular momentum. From this framework, the ladder operators for the orbital angular momentum can be solved as simultaneous eigenvectors of the Lie derivations ad(L-2) and ad(L-z) in an operator space. The ladder operators for solvable central potentials can also be found in a united way.
