## Abstract

A conventional type of neutron polarimeter consisting of three 12.5 × 12.5 cm cylindrical liquid scintillators and two 12.5 × 12.5 cm cylindrical plastic scintillators has been used to measure the transverse polarization transfer coefficient K_{yy} in the (p, n) reaction in the energy range 50 < E_{p < 80 MeV}. The effective analyzing powers of this polarimeter have been obtained empirically by observing neutrons from the ^{6}Li(p, n)^{6}Be reaction at θ = 0° and E_{p} = 50,65 and 80 MeV whose polarizations are deduced from the K_{yy} values of the ^{6}Li(p,p′)^{6}Be^{*} (0^{+} reaction by utilizing the analogue relation. Observed effective analyzing powers are significantly reduced particularly at high energy, most likely due to the ^{12}C(n,np)^{11}B reaction process. The double scattering efficiencies are 6 × 10^{-4} and 3 × 10^{-4} with effective analyzing powers of 0.14 and 0.11 at E_{n = 45} and 75 MeV, respectively.
