Cross section versus time delay and trapping probability

G. A. Luna-Acosta, A. A. Fernández-Marín, J. A. Méndez-Bermúdez +1

We study the behavior of the $s$-wave partial cross section $\sigma (k)$, the Wigner-Smith time delay $\tau (k)$, and the trapping probability $P(k)$ as function of the wave number $k$. The…
