Abstract
Jet rates in deep inelastic electron proton scattering are studied wit h the H1 detector at HERA for momentum transfers squared between 10 an d 4000 GeV2. It is shown that they can be quantitatively described by perturbative QCD in next to leading order making use of the parton den sities of the proton and with the strong coupling constant alpha(s) as a free parameter. The measured value, alpha( )(M(Z)(2)) = 0.123 +/- 0 .018, is in agreement both with determinations from e(+)e(-) annihilat ion at LEP The using the same observable and with the world average.
