Feasibility study of the quasi-free creation of the eta-prime meson in the reaction pn --> pn eta-prime

The feasibility of an investigation of the pn --> pn eta-prime reaction by means of the COSY-11 internal target facility is discussed. Appraisals are based on the assumption of the quasi-free reactions of beam protons, circulating in the cooler synchrotron COSY, with neutrons from a windowless deuteron cluster target.
