Abstract
The production of K+-mesons in proton-nucleus interactions at projectile energies far below and above the free nucleon-nucleon threshold of 1.58 GeV has been investigated using the ANKE spectrometer at COSY-Jülich. Double differential cross sections of K+ production have been obtained for diamond, copper and gold strip targets and beam energies Tp=1.0…2.3 GeV. At Tp=1.0 GeV the complete momentum spectrum of kaons emitted at forward angles (θ⩽12°) has been measured. The analysis of the target-mass dependence of the cross sections does not allow unambiguous conclusions about the underlying reaction mechanisms. Therefore, further measurements at forward emission angles, in particular of coincident K+p and K+d pairs, are needed.
