Description

Subthreshold K+ production cross sections have been measured in symmetric Ne+NaF, Ni+Ni, and Au+Au collisions at 1.0A GeV. The mass dependence is strong, close to A2. The angular distributions are nonisotropic in the center-of-mass system. Introducing rescattering seems to explain this effect to a large extent. copyright 1996 The American Physical Society
