K+ meson production in pA (A = C, Cu, Au) collisions has been studied using the ANKE spectrometer at an internal target position of the COSY-Juelich accelerator. The complete momentum spectrum of kaons emitted at forward angles, theta < 12 degrees, has been measured for a beam energy of T(p)=1.0 GeV, far below the free NN threshold of 1.58 GeV. The spectrum does not follow a thermal distribution at low kaon momenta and the larger momenta reflect a high degree of collectivity in the target nucleus.

Subthreshold production of low momentum K+ in p + C at 1.2-GeV.

The double differential cross section of low momentum kaons ( ≤0.3GeV/c) from p+C collisions at subthreshold bombarding energies has been for the first time measured by the use of the CLAMSUD magnetic spectrometer installed at the CELSIUS storage ring. Invariant cross sections extracted from the data show a source rapidity shifted below the nucleon-nucleon rapidity, in agreement with the existence of multistep processes in the K+ production cross section. The total cross section of the inclusive reaction 12C(p,K+) at 1.2 GeV was extracted and compared with recent data systematics as a function of the proton bombarding energy.
