Comparison of the experimental data from Cao et al. [17 in paper], with the theoretical results (a) obtained with the SBG parameters of Groot et al. [37 in paper], (b) with the PNH parameters of Hodgson and co-workers [36 in paper], and (c) with the PNA parameters [44]. In all cases the horizontal arrows and the numbers indicate the energy spacings between the interpolated values of the theoretical results and the actual experimental values. The blue lines show the interpolated curves of the computed data.
