Abstract
The direct constraint on the parameters of short range
pseudomagnetic interaction of free neutron with matter is obtained from the
recent test experiment on a search for neutron EDM by crystal-diffraction
method [1voron-dedm_test]. It is shown that this constraint on a
product of scalar to pseudo-scalar coupling constants gS gP is better
than that of any other method for the range λ < 10-5 cm.
