Self-Adjoint Ladder Operators. II

The method of self-adjoint ladder operators introduced in Part I has been used to study the isotropic harmonic oscillator and both the nonrelativistic and relativistic (Dirac) Kepler problems in a space of $n$ dimensions. In addition, a brief discussion of the dynamical (noninvariance) group $0\left(\right(n+1\mathrm{}), 1)$ of the $n$-dimensional nonrelativistic Kepler problem has been included.
