Investigating critical symmetries in Nd isotopes

We have just started looking at systematics to trace down values predicted by critical symmetries in nuclei measured in experimental works. First attempt is looking at the ratio E(4+)/E(2+) as a function of the mass number A. Several other observables will be checked, but so far here is a nice graph
