Coexistence and 2n transfer in even Zr nuclei

Abstract

In a simple coexistence model, I have examined $2n$ transfer ratios of ${0}^{+}$ states in even Zr nuclei. Results indicate that mixing is small in $^{96}\mathrm{Zr}$, but larger and nearly equal in $^{92,94}\mathrm{Zr}$, with $^{90}\mathrm{Zr}$ slightly larger. The $^{96}\mathrm{Zr}$ result is consistent with earlier analyses of E2 strengths.
