On the extraction of fission mode properties from fragment mass distributions
Patrick McGlynn, Cedric Simenel
Background: Fission modes are typically characterised by fragment mass and total kinetic energy centroids, around which a distribution of these variables is observed. These distrib…
Shell Effects in Quasi-fission in Reactions Forming 226Th Compound Nucleus
Hyeonseop Lee, Patrick McGlynn, Cedric Simenel
Quasi-fission (QF) reactions occur in fully damped heavy-ion collisions without the formation of an equilibrated compound nucleus, leading to the formation of fragments with simila…
Fission of Hg and Fm: a comparative study
Bernard Remi, Simenel Cedric, Blanchon Guillaume +2
Hg is experimentally found to fission asymmetrically. This result was not expected as a naive fragment shell effects study would support the symmetric mode to be the most p…
Quantum corrections to tunnelling amplitudes of neutral scalar fields
Rosemary Zielinski, Patrick McGlynn, Cedric Simenel
Though theoretical treatments of quantum tunnelling within single-particle quantum mechanics are well-established, at present, there is no quantum field-theoretic description (QFT)…
Tunnelling amplitudes through localised external potentials from Feynman diagram summation
Rosemary Zielinski, Cedric Simenel, Patrick McGlynn
Currently there is no general theory of quantum tunnelling of a particle through a potential barrier which is compatible with QFT. We present a complete calculation of tunnelling a…
