摘要：

The elastic scattering of negative kaons on polarized protons has been investigated in the range of kaon momenta 1.4-2.4 GeV/c. Measurements of intensity and polarization angular distributions are presented for 19 incident momenta in this range. The results are parametrized in Legendre expansion coefficients. The possibility of extracting resonance parameters from the data is discussed. A common feature of the distributions is the occurrence of two dips in the differential cross sections, accompanied by zero crossings in the polarizations. The first dip and zero crossing is at -t = 0.78 (GeV/c)2, independent of incident momentum: the second dip and zero crossing is at -u ≈ 0.3 (GeV/c)2, also independent of incident momentum. © 1968.
