摘要：

Recent very precise data on the K0 regeneration amplitude in carbon at high energy are analysed, together with lower-energy data. Their energy dependence is significantly different from that of the ω Regge exchange term in K N scattering, showing unambiguously the influence of nuclear effects at the level of a «secondary» Regge contribution. The origin of these effects is discussed within the framework of the multiple-scattering theory. From a theoretical point of view, one expects the ω-pomeron nuclear cut to lower the effective ω intercept in carbon; however, this possible qualitative explanation is not supported by qualitative calculations. A purely phenomenological analysis reveals that the effect observed is mainly due to the energy variation of the inelastic contributions to the double-scattering term. © 1978 Società Italiana di Fisica.
