Query: Investigation of the role of shell structure in quasi-fission mass
  distributions   Systematic measurements of mass-ratio distributions for fission following
collisions of $^{48}$Ti projectiles with even-even target nuclei from
$^{144}$Sm to $^{208}$Pb have been made at sub-barrier energies. They show the
presence of quasifission, and depend strongly on target nucleus deformation and
the fissility of the composite nucleus. A new framework to analyse systematic
mass-ratio measurements allows direct comparison with the trends expected from
shell structure, independent of assumptions or fits. This indicates that
quasi-fission mass distributions show trends consistent with low energy
mass-asymmetric fission of the same actinide elements.
