Abstract

In a typical nuclear elastic scattering experiment, differential cross section is very sensitive to the scattered angle and therefore the main source of systematic errors come from a millimetric uncertainties in the position measurement of detectors. A method for detector misalignment correction has been successfully applied to the elastic scattering of ⁷Be on Pb target at E_lab=17.9 MeV/u at Radioactive Ion Beam Line in Lanzhou (RIBLL) at Heavy Ion Research Facility in Lanzhou (HIRFL). The correction method is based on the fact that the ratio of elastic scattering and Rutherford cross sections should be independent of scattering angle, and equal to unity for very forward angles. A Monte Carlo simulation was performed to examine the angular distribution of cross sections for a given shift of detector position.
