Project description
In this project, we propose to implement a gravitational spectroscopy for studies of quantum properties of ultra-cold atomic hydrogen and its interactions with matter and gravity. We are going to build a magnetic trap for cooling a large number of H atoms below 1 microKelvin. We will release ultra-slow atoms from the trap onto the cold surface of superfluid helium. Owing to the weakest interaction potential such surface provides nearly perfect reflecting conditions for low-energy atoms. This will allow studies of quantum bounces and stationary gravitational states of H atoms in the potential well created by this surface and the field of Earth gravity. The methods and ideas of this project will be useful for making similar experiments with antihydrogen utilizing a new source and trap for H ¯currently prepared in CERN.
