Measurement of the reactions K/sup +/d to K/sup +/d and K/sup +/d to K /sup +/pn and an investigation of elastic K/sup +/-nucleon scattering at 46 GeV/c

The coherent elastic reaction K/sup +/d to K/sup +/d and the break-up reaction K/sup +/d to K/sup +/pn are st studied in a K/sup +/d experiment at 4.6 GeV/c with the CERN 2 m bubble chamber. Partial and differential cross sections are given and the slopes of the differential cross sections are determined. The results for the reaction K/sup +/d to K/sup +/p(n/sub s/), where n/sub s/ denotes the spectator neutron, are compared with those of the reaction K/sup +/p to K/sup o/pp and K/sup +/p to K/sup +/p, parameters of the elastic K /sup +/-nucleon scattering at 4.6 GeV/c are determined in the framework of the Glauber model. The D-wave of the deuteron and spin- flip effects are taken into account. (17 refs).
