The AEgIS experiment located at the Antiproton Decelerator at CERN aims to measure the gravitational fall of a cold antihydrogen pulsed beam. The precise observation of the antiatoms in the Earth gravitational field requires a controlled production and manipulation of antihydrogen. The neutral antimatter is obtained via a charge exchange reaction between a cold plasma of antiprotons from ELENA...
The primary goal of the AEgIS experiment at CERN is to measure the gravitational acceleration on neutral antimatter. Positronium (Ps), the metastable bound state of an electron and a positron, is a suitable candidate for a force-sensitive inertial measurement by means of deflectometry/interferometry. In order to conduct such an experiment, the impact position and time of arrival at the...
Determining the ratio of carbon-to-oxygen produced at the end of the helium burning in stars is a paramount importance problem for nuclear astrophysics. In recent years, the advent of high-intensity $\gamma$-ray beams opened a new opportunity to study the $^{12}$C($\alpha$,$\gamma$)$^{16}$O reaction regulating the ration by investigating the time-reversal photodisintegration reaction.
To take...
In this contribution, the Compton scattering of entangled annihilation photons is discussed. The pairs of gammas with energy 511 keV are born in electron-positron annihilation and have the entangled polarization states. Since the Compton scattering depends on the polarization of the initial photon, one can expect to observe the peculiar properties of the Compton scattering of entangled gammas....
