…side). For even A , the pairing term splits the curve into two parabolas — one for even-even nuclei sitting lower in mass (more bound), one for odd-odd nuclei sitting higher — offset from each other by roughly 2\, . This is the double-parabola structure behind one of the chart’s more striking features: a modest number of even mass numbers host two, and even three, beta-stable even-even isobars side by side, because an odd-odd nucleus between them would have to climb over the even-even parabola’s…
