摘要：

The quasi-free np charge-exchange reaction p (d) over right arrow -> {pp}(s)n has to be employed to extend the investigations of np scattering at ANKE to the highest energy available at COSY. As the proof-of-principle experiment, the initial research has been conducted at proton energy T-p = 600 MeV using a polarized Deuterium target. The vector and tensor analyzing powers A(y) and A(yy) were measured for momentum transfers q >= 160 MeV/c. These data connect smoothly with the previous measurements at q <= 140 MeV/c performed using a polarized deuteron beam. The reported data are well reproduced by the impulse approximation using the SAID np amplitudes. The results therefore proves that it is possible to continue the np programme at higher energies at ANKE.
