Measurement of structure-function ratios on isoscalar targets

In the framework of the present thesis an analysis of the structure-function ratios of the deep inelastic muon scattering on isoscalar targets (6Li, 12C, 40Ca) is treated. The data set taken up at a muon beam energy of 90 GeV exhibits low statistical errors. Beside it contains because of the principle of complementary targets a comparably low systematic error. The kinematically covered range lies in x between 0.01-0.7 and in the four-momentum transfer Q2 at 1-20 GeV2. The kinematical dependences of structure-function rations as well as the dependence on the mass number A of the three targets were studied. Differences of structure functions were formed by means of the measured ratios. (orig./HSI)
