Measurement of the depolarization parameter Kyy′ in p2H elastic scattering at Ep = 65 MeV

Abstract The depolarization parameter K y y ′ in the elastic scattering of 65 MeV polarized protons from deuterium has been measured using a newly designed spectrograph and a multi-foil polarimeter. The measured K y y ′ values are well reproduced by a Faddeev calculation using the NN interaction in a separable representation with a tensor force which reproduces the empirical mixing parameter of the 3 S 1  3 D 1 partial waves.
