Novel analysis of proton-$\gamma $ coincidences for the $\beta $-delayed proton emission technique: the case of 46Mn
Abstract
In the interest of exploring resonant contributions to the radiative capture reaction 45 45 V(p, γ γ ) 46 46 Cr, which is identified to impact the 44 44 Ti nucleosynthesis in Core Collapse Supernovae at astrophysical energies, we performed a spectroscopic study of 46 46 Cr through the β β -decay of the progenitor 46 46 Mn. We present new results on the decay scheme of the proton-rich exotic nucleus 46 46 Mn based on a new approach at the level of the experimental data analysis. 46 46 Mn was produced among other nuclei at the LISE3 fragment separator operated in GANIL using the fragmentation technique. The novel approach is compared with a traditional data analysis, and validated using the known decay scheme of 45 45 Cr. The observed level scheme of the nucleus 46 46 Cr is compared with previous works. This work confirms former experimental results, while presenting better statistics and revealing new transitions in the decay scheme.
