Two-Pion Production in Proton-Proton Collisions -- Experimental Total Cross Sections and their Isospin Decomposition
T. Skorodko, M. Bashkanov, D. Bogoslawsky +37
The two-pion production in pp-collisions has been investigated at CELSIUS in exclusive measurements from threshold up to = 1.36 GeV. Total and differential cross sections hav…
Exclusive measurement of two-pion production in the dd --> 4Hepipi reaction
S. Keleta, Chr. Bargholtz, M. Bashkanov +46
The results from the first kinematically complete measurement of the dd --> 4Hepipi reaction are reported. The aim was to investigate a long standing puzzle regarding the origin of…
Single-Pion Production in pp Collisions at 0.95 GeV/c (II)
S. Abd El-Samad, R. Bilger, K. Th. Brinkmann +41
The single-pion production reactions , and were measured at a beam momentum of 0.95 GeV/c ( 400 MeV) using the short version of…
Double-Pionic Fusion of Nuclear Systems and the ABCEffect -- Aproaching a Puzzle by Exclusive and Kinematically Complete Measurements
M. Bashkanov, C. Bargholtz, M. Berlowski +46
The ABC effect - a puzzling low-mass enhancement in the invariant mass spectrum - is well-known from inclusive measurements of two-pion production in nuclear fusion reactions.…
Anisotropy in the pion angular distribution of the reaction pp -> pp pi0 at 400 MeV
P. Thorngren Engblom, S. Negasi Keleta, F. Cappellaro +23
The reaction pp -> pp pi0 was studied with the WASA detector at the CELSIUS storage ring. The center of mass angular distribution of the pi0 was obtained by detection of the gamma…
