Negative pion stopping in ultra dense and hot DT targets of ICF fast ignition concern

In order to implement a Scenario of π^- catalysis of Deuterium-Tritium (DT) thermonuclear reactions in a dense and hot precompressed target plasma envisioned in the Intertial Confinement Fusion (ICF) fast ignition approach, we pay detailed attention to the stopping of negative pions arising from electro-disintregration of target D and T nuclei by ultra-relativistic e-beams. Emphasis is put on a mostly non-relativistic pion velocity regime (E <= 10 MeV).
