Book The Two Pion Exchange Contribution to   Production in Proton proton Collisions at 970 Mev

Download or read book The Two Pion Exchange Contribution to Production in Proton proton Collisions at 970 Mev written by Melvin Month and published by . This book was released on 1964 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Two distinct theoretical attempts have been made to describe the neutron distribution for the process of [pi]+ production in proton-proton collisions at 970 Mev. The OPE and OBE Models both are one particle exchange theories. Trying to extend the former, using its production vertex technique, leads to divergent integrals. However, using in part the perturbation methods of the OBE model, a finite two pion exchange term is realized. It is found, contrary to the assumption made in the OBE model, that the two pion term gives a contribution greater than the one pion term. (In calculating the two pion term the [pi]-[pi] interaction in the crossed channel is neglected. This has been taken into account in the OBE model by the exchange of multipion resonances considered as particles in the usual sense.) This result invalidates the claim that the OBE model completely accounts for the dominant contributions to the production process under consideration here. In the light of this fact it is suggested that the fundamental tenets of the OBE model be subjected to critical scrutiny. Further, because of the close relationship between the OPE model and the one pion term of the OBE model, it is inferred that the former is also in need of reevaluation. [...]" --

Book Parameterizations of Pion Energy Spectrum in Nucleon Nucleon Collisions

Download or read book Parameterizations of Pion Energy Spectrum in Nucleon Nucleon Collisions written by National Aeronaut Administration (Nasa) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-10 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of pion (PI) production are expected to play an important role in radiation exposures in the upper atmosphere or on the Martian surface. Nuclear databases for describing pion production are developed for radiation transport codes to support these studies. We analyze the secondary energy spectrum of pions produced in nucleon-nucleon (NN) collisions in the relativistic one-pion exchange model. Parametric formulas of the isospin cross sections for one-pion production channels are discussed and are used to renormalize the model spectrum. Energy spectra for the deuteron related channels (NN yields dPi) are also described. Cucinotta, Franics A. and Wilson, John W. and Norbury, John W. Langley Research Center...
