The study of mirror symmetry has been extended to the Tz=±1/2 nuclei 45V and 45Ti using a 24
Mg + 24
Mg fusion‐evaporation reaction at the Vivitron accelerator at IReS Strasbourg. In order to extend the study to more‐exotic nuclei, a new experimental technique using fragmentation of a secondary beam has been tried at GSI. The aim was to study excited states in 53
Ni using fragmentation of a 55
Ni beam produced in the initial fragmentation of 600 MeV/A 58
Ni by a 9Be target. Details and results of both experiments will be presented.
