Abstract
A method of using a gravitational 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 ultracold neutrons with atoms of noble gases (He, Ne, Ar,
86Kr) and the data on the coherent neutron scattering length of the
nucleus. The first result of such type analysis is presented.
