Diffraction enhancement effect and new possibilities of measuring the electric charge of the neutron and its inertial-to-gravitational mass ratio
- Russian Academy of Sciences, St. Petersburg Nuclear Physics Institute (Russian Federation)
Diffraction enhancement of small effects affecting a neutron undergoing Laue diffraction at Bragg angles {theta}{sub B} close to 90 deg. is predicted and experimentally observed. The enhancement is due to the delay of the neutron inside the crystal during diffraction and is proportional to tan{sup 2{theta}}{sub B}. As a result, the diffraction enhancement factor may be as large as {approx}10{sup 8}-10{sup 9}. On this basis, a new method is proposed for searching for the electric charge of the neutron and for measuring the ratio of its inertial mass m{sub i} to the gravitational mass m{sub G}. It is shown that the accuracy of the neutron charge measurement can be improved by more than two orders of magnitude in relation to the present-day accuracy and that the ratio m{sub i}/m{sub G} can be measured to an precision of {sigma}(m{sub i}/m{sub G}) {approx} 10{sup -6}.
