Search for quantum states of a neutron in the Earth gravitational field, using a high precision one-component gravitational neutron spectrometer, and development of related experimental methods

Cel

In the framework of the presented project we intend to measure, for the first time, quantum states of a neutron, in the trap between the Earth's gravitational field and the surface of Fermi quasi-potential. No other quantum state in a gravitational field was yet measured. The neutron counting rate at the position sensitive detector was measured in first test experiment to be high enough (~0,01-0,1 neutrons/c) for identification of this very interesting phenomenon and its study for a reasonable measuring time.
The experiments will use a high precision one-component gravitational neutron spectrometer with the best currently available space and energy resolution (1,5 mm and ~0,15peV respectively). This device and the related methods are also developing in the framework of the present project. The developed technique and, may be, the quantum phenomenon itself promise to be very useful in researches with UCN. It can push forward the whole range of UCN studies with high resolution.

For instance, several other related pilot experiments are planed:
1) Investigation of specular reflections of UCN from mirrors for estimation of increase in accuracy of check of electrical neutrality of a neutron. If the reflections of UCN from mirrors are highly specular then the gain in sensitivity could be very considerable, at least 10 times. Such an experiment would use with long storage of UCN at specular trajectories between mirrors in electric field;
2) Measurement of possible UCN spectra evolution following from introduction of non-linear logarithmic term in the Shrodinger equation (hypothesis proposed by A.Steyerl) with accuracy at least 10 times higher then that currently measured.

At the end of the project a detailed general review of these research will be published.
