Findings

Initial beta decay analysis results obtained.

Evidence supporting isospin symmetry in A=54 nuclei.

Comparison between charge exchange and beta decay data.

Abstract

Under the assumption that isospin is a good quantum number, symmetry is expected for the transitions from ground state of the pair T=1, T$_Z$=$\pm$1 nuclei to the excited states of the T=0 nucleus situated betweem them. To study the isospin symmetry of these transitions in mass A=54, we have performed two different experiment: 1) High resolution charge exchange reactions at RCNP (Osaka) for the T$_Z$=+1 $\rightarrow$ 0. 2) $\beta$-decay experiment a Louvain la Neuve. \\ The present work shows the first results in the analysis of the $\beta$-decay experiment as part of the Diploma and PhD thesis of Francisco Molina Palacios at Instituto de Fisica Corpuscular in Valencia.
