Abstract
In this note the two dimensional Dirac operator A η with an electrostatic δ-shell interaction of strength η∈ R supported on a straight line is studied. We observe a spectral transition in the sense that for the critical interaction strengths η= ± 2 the continuous spectrum of A η inside the spectral gap of the free Dirac operator A collapses abruptly to a single point.
