Abstract Differential and total cross sections of the p + p → π+ + d reaction close to threshold were measured employing a magnetic spectrograph with track reconstruction, a very thin liquid hydrogen target and an accelerated proton beam with high phase space density. The data resolve a previous discrepancy between the n + p → π0 + d and the π+ + d → 2p reaction close to threshold indicating that isospin symmetry may be broken in the s-wave part of the cross section.

Large angle elastic scattering of 9Be ions on carbon isotopes

Abstract The differential cross sections for elastic scattering of 9 Be on the carbon isotopes 12 C and 13 C were measured at two different energies (11.4 and 14.9 MeV c.m.). The anomalously high cross sections for backward angles are explained as contributions of 3 He and 4 He exchange processes. The calculations were performed with an optical model for potential scattering and a finite range DWBA model for the transfer processes.
