Electron Capture of $$^8$$ 8 B into Highly Excited States of $$^8$$ 8 Be

Abstract

Energy differences between analogue states in the T=1/2 23 Mg-23 Ma mirror nuclei have been measured along the rotational yrast bands with the EXOGAM + Neutron Wall + DIAMANT setup at GANIL. The nuclei of interest have been populated via the 12 C+ 16 O fusion evaporation reaction. This allows us to search for effects arising from isospin-symmetry breaking interactions (ISB) and/or shape changes. Data are interpreted in the shell model framework following the method successfully applied to nuclei in the f 1/2 shell.
