Around 10^7 scattering events were collected at the 40 m small angle neutron scattering beam line located at the HANARO research reactor of the Korean Atomic Energy Research Institute. The extracted coupling strengths of new forces in the Yukawa-type parametrization are g^2 = (0.2 6.8 2.0) 10^-15 GeV^2 and g^2 = (-5.3 9.0 + 2.7 -2.8) 10^-17 GeV^2 for interaction ranges of 0.1 and 1.0 nm, respectively. These strengths correspond to 95\% confidence level limits of g^2 < (1.4 0.2) 10^-14 GeV^-2 and g^2 < (1.3 0.2) 10^-16 GeV^-2, improving the current limits for interaction ranges between 4 and 0.04 nm by a factor of up to 10.
