A method of using a gravitational UCN spectrometer to search for long-range forces between neutrons and atoms is proposed. The constraints on the strength of long-range forces within the range of 10-10 - 10-4 cm can be obtained from the experiments on measurements of the total cross section of interaction of UCN with atoms of the noble gases (He, Ne, Ar, Kr) and the data on the coherent neutron scattering length of the nucleus. The first result of such an analysis is presented. Further prospect of UCN method is discussed.
