| Abstract: | We calculate the diffraction slope B
D
for diffractive deep inelastic scattering. We find a counterintuitive rise of B
D
in going from exclusive diffractive excitation of vector mesons to excitation of continuum states with M
2∼Q
2. For the small-mass continuum we predict a rapid variation of B
D
with M
2 on a scale of m
V
2
and a sharp drop of B
D
for a small-mass continuum above the vector meson excitation.
