Figure 1

Representative experimental Mallmann correlation plots for the band structures of different nuclei: even-even (the g.s.b.), odd-$A$, and odd-odd, as indicated (note the vertical shift of the odd-$A$ and odd-odd data). The continuous lines through the even-even data are spline interpolations, and are drawn (correspondingly shifted) also through the odd-$A$ and odd-odd data to guide a comparison with the even-even case. The dashed lines are the “Ejiri” straight lines [prediction of the Ejiri formula or of Eq. (1)]. Note that the data for odd-$A$ nuclei contain points with $R(j+4/j+2)$ values up to 78 (not shown), which are close to the Ejiri lines.Reuse & Permissions

Figure 2

Comparison between the experimental Mallmann ratios and those calculated with Eq. (4). The insets show the distributions of the $R(j+2n/j+2){}_{\exp }/R(j+2n/j+2){}_{\mathrm{calc}}$ values, counted with a bin value of 0.005.Reuse & Permissions
