Description

We report updates of experimental constraints on new gravity-like interactions by measuring the angular distribution of cold neutrons scattering off atomic xenon gas. The results improved previous upper limit on Yukawa-type parametrization space in the 4 to 0.04 nm range by a factor of up to 10[1]. We also discuss about our plans of a test of the weak equivalence principle and a new force search in the micron range, using a neutron quantum bouncing system[2]. [1] Y. Kamiya, K. Itagaki, M.
