16 May 2001 | Journal: | Phys.Rev.Lett. 87 (2001) 022301 | Subject: | nucl-ex | Abstract: | 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. | Source: | arXiv, nucl-ex/0105008 | Services: | Forum | Review | PDF | Favorites |
