The yields should be integrated again using the final set of matrixelements in order to make an accurate comparison with the original experimental data and toensure that the point approximation remains valid at the chi-squared minimum. (In some cases asecond iteration of the fit may be required. Refer to the tutorial in this chapter.)Experiments 4-26 skipped for brevity.CALCULATED AND EXPERIMENTAL YIELDS EXPERIMENT 27 DETECTOR 1NI NF II IF ENERGY(MEV) YCAL YEXP PC. DIFF.
