The doubly-differential cross sections for the pp-->ppη and pd-->ηX reactions have been measured at incident proton energies of 1.3 and 1.5 GeV. The ratio of the pd to pp-induced cross sections varies from about 8-10 at 1.3 GeV to 4.5-6 at 1.5 GeV in the η kinetic energy interval 100 MeV <=Tη<=220 MeV. Information on the pn-->ηX reaction has been extracted from these measurements within the framework of a simple folding model.

Abstract
The doubly-differential cross sections for the pp-->ppη and pd-->ηX reactions have been measured at incident proton energies of 1.3 and 1.5 GeV. The ratio of the pd to pp-induced cross sections varies from about 8-10 at 1.3 GeV to 4.5-6 at 1.5 GeV in the η kinetic energy interval 100 MeV <=Tη<=220 MeV. Information on the pn-->ηX reaction has been extracted from these measurements within the framework of a simple folding model.
