Differential cross sections and a complete set of polarization observables have been measured in the quasielastic 2H(p,n) reaction at a bombarding energy of 345 MeV and laboratory scattering angles of 16°, 22°, and 27°. The data are compared with plane-wave impulse approximation calculations employing an optimal factorization approximation. The agreement between the experimental and theoretical results validates these approximations in the present momentum- and energy-transfer regions. The experimental spin-longitudinal and spin-transverse response functions, R L and RT, respectively, are deduced from the data. The obtained RT is consistent with that obtained from the quasielastic electron scattering. The theoretical calculations with the Reid soft core potential give good descriptions for RL and RT, whereas the latter is slightly underestimated around the quasielastic peak.
