TL;DR: The GBAR project at CERN as mentioned in this paper measured the free fall acceleration of ultracold neutral anti hydrogen atoms in the terrestrial gravitational field, which consists preparing anti hydrogen ions (one antiproton and two positrons) and sympathetically cooling them with Be (+) ions.
Journal ArticleDOI
A quantum mechanical description of the experiment on the observation of gravitationally bound states
Alexander Westphal,Hartmut Abele,S. Baeßler,Valery Nesvizhevsky,K.V. Protasov,Alexei Voronin +5 more
TL;DR: In this article, a quantum mechanical scattering model for the earth's gravitational field is presented, with ultra-cold neutrons falling under gravity, and the experimental results can be described by the quantum mechanics scattering model.
Journal ArticleDOI
Neutron whispering gallery
TL;DR: In this paper, a structure that allows neutrons to be trapped in long-lived "whispering gallery" states provides scientists with a potentially useful tool to study the interaction of neutrons with matter.

TL;DR: The GBAR project as mentioned in this paper proposes to measure the free fall acceleration of neutral antihydrogen atoms in the terrestrial gravitational field by photoionizing them with Be+ ions to a few 10 μ K.
