Spinor tunnelling amplitudes from all-order Feynman diagram summation
Max Fleming, Cedric Simenel
This work presents a non-perturbative quantum field theoretic computation of spinor tunnelling through a potential barrier. Within position space potential formalism, we identify c…
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…
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…
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…
Hartree-Fock-Bogoliubov study of quantum shell effects on the path to fission in Hg, U and Fm
Rémi Bernard, Cédric Simenel, Guillaume Blanchon
Quantum shell effects stabilising fission fragments with various shapes have been invoked as a factor determining the distribution of nucleons between the fragments at scission. Sh…
Smoothing of one- and two-dimensional discontinuities in potential energy surfaces
N. -W. T. Lau, R. N. Bernard, C. Simenel
Background: The generation of potential energy surfaces is a critical step in theoretical models aiming to understand and predict nuclear fission. Discontinuities frequently arise…
