Abstract

Eigenvalue problems for radial Dirac equation are treated by expanding wavefunction over kinetically balanced B-splines. Spurious states which may appear in the eigenvalue problem hardly occur, and the present calculation is effective to calculate energy for bound-state and to prepare a set of eigenstates.
