Inelastic neutron scattering on solid ¹³⁰XeF₂ and ¹³⁶XeF₂ targets was utilized to populate excited levels in ¹³⁰Xe and ¹³⁶Xe. When calculating nuclear matrix elements vital to the understanding of double-beta decay, it is important to have a clear understanding of the low-lying level structure of both the parent and daughter nucleus. Of particular relevance to double-beta decay searches are the assignments of 0⁺ states. We show here that in the case of ¹³⁰Xe there are several discrepancies in the adopted level structure. We found that one previous 0⁺ candidate level (1590 …
