Calculating broad neutron resonances in a cut-off Woods-Saxon potential | Á. Baran

25 Feb 2015 | Abstract: | In a cut-off Woods-Saxon potential with realistic depth $S$-matrix poles
being far from the imaginary wave number axis form a sequence where the
distances of the consecutive resonances are inversely proportional with the
cut-off radius value. Other poles lying closer to the imaginary wave number
axis might have trajectories with irregular shapes as the depth of the
potential increases. Poles being close repel each other, and their repulsion is
responsible for the changes of the directions of the corresponding
trajectories. The interaction is extremely sensitive to the cut-off radius
value. The repulsion might cause that certain resonances become antibound and
later resonances again when they collide on the imaginary axis. | Source: | arXiv, 1502.7111 | Services: | Forum | Review | PDF | Favorites |
