Abstract

Pairing plays a crucial role in the microscopic description of nuclear fission. Microscopic methods provide access to three quantities related to pairing, namely, the pairing gap ($\Delta$), the particle number fluctuations ($ \Delta \hat{N}^2 $), and the quenching factor (QF). The aim of this work is to analyse the impact of each of these quantities on the static description of the fission process.
