During the E666 experiment at the GANIL facility in 2016, where the fragmentation technique of a primary \ (^58\) Ni beam was used, \ (^46\) Mn, as well as other isotopes, was created and later implanted in a DSSSD surrounded by HPGe clovers. The subsequent \ (^+\) -decay could populate \ (^46\) Cr excited states above the proton separation energy, and later decay into \ (^45\) V in a process called \ (\) -delayed proton emission. The detection of the \ (\) rays and protons emitted after the \ (^46\) Mn decay allowed us to study the inverse reaction to the \ (^45\) V (\ (p, \) ) \ (^46\) Cr process. This later reaction impacts the \ (^44\) Ti production in Supernovae events. In this work, we present the preliminary results regarding the refined energy spectrum for the \ (\) rays and charged particles detected, linked to the \ (^46\) Mn \ (^+\) -decay.
