Abstract

Two different interactions give similar results for excitation energies and g factors of 2⁺₁ states for most even-even argon isotopes except ⁴⁶Ar. This is explained in terms of an inversion in J=1/2⁺ and levels in ⁴⁷K which is successfully obtained by one of the interactions but not the other. This example shows the possible dangers of nuclear astrophysics extrapolations.
