Abstract
The chameleon scalar field is considered as a possible cause of
accelerated expansion of the Universe. The chameleon field induces an
interaction potential between particle and massive body. Previous
experiments with falling cold neutrons intended to measure the neutron
coherent scattering lengths and verification of the weak equivalence
principle for the neutron are used to constrain the parameters characterizing
the strength of the scalar chameleon fields.
