The question whether there is a pion transparency in 500 MeV C(π, π ′ ) scatterings is studied using a semiclassical, hadronic transport model. The double differential cross sections of this reaction measured at LAMPF can be largely accounted for, if one uses energy-dependent, anisotropic angular distributions which are fitted to pion-nucleon scattering data for the decay of ∆(1232) and N(1440)...

Dose equivalent from 500 MeV neutrons

Neutrons constitute a major component in the radiation fi eld outside the shielding of particle accelerators. Consequently appropriate neutron dose meters are needed to survey the radiation levels. A thermo-luminescence based neutron dosemeter is used at the UNILAC as well as at the SIS. It has been modifi ed to improve the response for high energetic neutrons (extended range). We report on a t...

′ π ) . . . reactions in nuclei

We study the inclusive (e, eN), (e, eNN), (e, eπ), (e, eπN) reactions in nuclei using a Monte Carlo simulation method to treat the multichannel problem of the final state. The input consists of reaction probabilities for the different steps evaluated using microscopical many body methods. We obtain a good agreement with experiment in some channels where there is data and make predictions for ot...

Double Pion Production Reactions

We report on reactions producing two pions induced by real and virtual photons or nucleons. The role of different resonances in these reactions is emphasized. Novel results on coherent 2π photoproduction in nuclei are also reported. 1 Double pion photoproduction on the nucleon. The γN → π+π−N reaction is attracting attentions of both theoretical and experimental groups and is bound to play a si...

Electromagnetic Shower Profile Measurements in Iron with 500 MeV Electrons

The longitudinal and lateral shower profiles for 500 MeV electrons in iron are studied using dosimetry and activation techniques. The results are compared with Monte Carlo simulations and other previously published data. The agreement between the data and the EGS4 simulation results is good; a simple shower profile parametrization of type kz exp (−βz) does not represent the experimental data we...
