摘要：

We clarify two issues related to the so-called D-term in matrix elements of the energy-momentum tensor. First, we show that in a stable system, the D-term can have either sign, contrary to claims that it must be negative. Second, we demonstrate a logarithmic enhancement of the alpha correction to the D-term in any state of the hydrogen atom. We contrast this enhancement with the Lamb shift where it is present only in S-states.
