A one-to-one comparison of the experiments: (a) comparison of experimental data from Hodgson and co-workers [ref 16 in paper] with experimental data from Luntz et al. [ref 15 in paper], (b) comparison of experimental data from Cao et al. [ref 17 in paper] with experimental data from Luntz et al. [ref 15 in paper], and (c) comparison of experimental data from Hodgson and co-workers [16] with experimental data from Cao et al. [ref 17 in paper]. In the all cases the horizontal arrows and the numbers indicate the energy spacings between the interpolated values of one experiment and the actual values of the other experiment. The dotted lines show the interpolated curve of one set of experimental data.
