Abstract
If a central vector potential in the Dirac equation is monotonic in a parameter , then a discrete eigenvalue is monotonic in . For such a special class of comparisons, this generalizes an earlier comparison theorem that was restricted to node free states. Moreover, the present theorem applies to every discrete eigenvalue.
