| Abstract |
New data are presented of the inclusive ep scattering cross section in the kinematic region of very low x and Q^2 ~ 1GeV^2, in the transition region from the nonperturbative to the deep inelastic domain. The data were taken with 920 GeV proton beam energy and 27.5 GeV electron beam energy, with the interaction vertex shifted by +70cm, thereby accessing a region of lower Q^2 than at nominal vertex position. The accuracy of the measurement is improved and the range of Bjorken x and of inelasticity extended as compared to previous shifted vertex data. The cross section measurement is used to obtain new data on the proton structure function F_2(x,Q^2). |
