Stochastic methods for zero energy quantum scattering
Autor: Hubertus R. Mall, Stefan Lenz, Justus H. Koch
Publikováno v: Computer Physics Communications, 108(2-3), 115-146. Elsevier
We investigate the use of stochastic methods for zero energy quantum scattering based on a path integral approach. With the application to the scattering of a projectile from a nuclear many body target in mind, we use the potential scattering of a pa

Corrections to the closure approximation for the optical potential
Autor: Justus H. Koch
Publikováno v: Nuclear Physics B. 66:464-481
Target closure is a basic assumption made at the outset of many derivation of the standard optical potential. Using the formalism of Foldy and Walecka we show how the target dynamics, neglected in the closure approximation, can be incorporated into t

Models forπ+−O16Scattering at 270 MeV
Autor: Justus H. Koch, Morton M. Sternheim
Publikováno v: Physical Review C. 6:1118-1120
Predictions of the Kisslinger and "local" optical models are compared to ${\ensuremath{\pi}}^{+}\ensuremath{-}^{16}\mathrm{O}$ elastic differential cross sections at 270-MeV lab kinetic energy. With no adjusted parameters, the local potential gives a

Photonuclear Reactions at Intermediate Energies
Autor: Justus H. Koch
Publikováno v: New Vistas in Nuclear Dynamics ISBN: 9781468451818
The characteristic feature of the pion-nucleon interaction at intermediate energies is the excitation of the ∆-resonance, the lowest excited state of the nucleon. This can clearly be seen by looking, for example, at the total π-N cross section as

Nuclear photoproduction of pions
Autor: Justus H. Koch
Publikováno v: AIP Conference Proceedings.
The focus of this paper is the resonant pion photoproduction mechanism. In the production to discrete final states, the character of the nuclear transition can be used to emphasize this aspect and therefore to increase the sensitivity to medium modif
