Abstract
An estimation of the spin-dependent part of the $np\to pn$ charge exchange amplitude was made on the basis of $dp\to (pp)n$ data, taken at 1.67 GeV/ c per nucleon in a full solid-angle arrangement. The $np\to pn$ amplitude turned out to be entirely spin-dependent. This result shows new possibilities for experiments using polarized deuteron beams and polarized proton targets.
