Experimental study of dynamics in the reaction

P Moskal, HH Adam, A Budzanowski… - Physical Review C …, 2004 - APS
A high statistics measurement of the pp→ pp η reaction at an excess energy of Q= 15.5 MeV
has been performed at the internal beam facility COSY-11. The stochastically cooled proton
beam and the used detection system allowed to determine the momenta of the outgoing
protons with a precision of 4 MeV∕ c (σ) in the center-of-mass frame. The determination of
the four-momentum vectors of both outgoing protons allowed to derive the complete
kinematical information of the η pp system. An unexpectedly large enhancement of the …
