ABSTRACT.  Taking into account relativistic
effects in quantum chemistry is crucial for accurate computations
involving heavy atoms. Standard numerical methods can deal with
the problem of {\rm variational collapse} and the appearance of {\rm
spurious roots} only in special cases. The goal of this letter is to
provide a general and robust method to compute particle bound states of
the Dirac equation.
