New applications of the Biedenharn-Temple operator
  The Biedenharn approach to the Dirac-Coulomb problem is applied to a system considered by D'Hoker and Vinet, which consists of a spin $\2$ particle in the combined field of a Dirac monopole plus a $\lambda^2/r^2$ potential. The explicit solution is obtained by diagonalizing the Biedenharn-Temple operator, $\Gamma$.
