Neutron-proton charge-exchange amplitudes at 585 MeV
D. Chiladze, J. Carbonell, A. Dzyuba +27
The differential cross section and deuteron analysing powers of the dp -> {pp}n charge-exchange reaction have been measured with the ANKE spectrometer at the COSY storage ring. Usi…
Coupled-channel effects in the pp -> ppK+K- reaction
A. Dzyuba, M. Buescher, M. Hartmann +6
The cross sections for the pp -> ppK+K- reaction were measured at three beam energies 2.65, 2.70, and 2.83 GeV at the COSY-ANKE facility. The shape of the K+K- spectrum at low inva…
Determination of target thickness and luminosity from beam energy losses
H. J. Stein, M. Hartmann, I. Keshelashvili +15
The repeated passage of a coasting ion beam of a storage ring through a thin target induces a shift in the revolution frequency due to the energy loss in the target. Since the freq…
Kaon Pair Production in Proton--Proton Collisions
Y. Maeda, M. Hartmann, I. Keshelashvili +23
The differential and total cross sections for kaon pair production in the pp->ppK+K- reaction have been measured at three beam energies of 2.65, 2.70, and 2.83 GeV using the ANKE m…
Is there an eta-3He quasi--bound state ?
C. Wilkin, M. Buescher, D. Chiladze +19
The observed variation of the total cross section for the dp -> 3He eta reaction near threshold means that the magnitude of the s--wave amplitude falls very rapidly with the eta ce…
Lineshape of the Lambda(1405) Hyperon Measured Through its Sigma0 pion0 Decay
I. Zychor, M. Büscher, M. Hartmann +12
The pp -> p K+ Y0 reaction has been studied for hyperon masses m(Y0)<1540 MeV/c2 at COSY-Juelich by using a 3.65 GeV/c circulating proton beam incident on an internal hydrogen targ…
