Effects of systematic errors in analyses of nuclear scattering data

Abstract

The effects of systematic errors in elastic scattering differential cross-section data upon the assessment of quality fits to that data have been studied. First, to estimate the probability of any unknown systematic errors, select, typical, sets of data have been processed using the method of generalized cross validation; a method based upon the premise that any data set should satisfy an optimal smoothness criterion. Specified systematic errors should also be taken into account when high quality fits to data are sought. We have considered such effects due to the finite angular resolution associated with the data in some quite exceptional, heavy ion scattering data sets. Allowing angle shift..
