Cooling of Rydberg H̄ during radiative cascade
نویسندگان
چکیده
We have simulated the centre-of-mass motion of Rydberg anti-hydrogen atoms in spatially varying magnetic fields. We find that a population of anti-hydrogen can lose substantial centre-of-mass kinetic energy during the radiative cascade to the ground state. The loss of energy is due to the change in magnetic moment when photons are emitted and is akin to adiabatic cooling. We also simulate the pattern of anti-hydrogen hits on the walls of the trap and find that the existence of trapped Rydberg atoms leads to a distinctive distribution along the trap axis.

Proposal for making a beam of antihydrogen by two charge exchange events
We have performed calculations of two successive charge transfers in a geometry that could generate a beam of antihydrogen atoms (H̄) or reliably produce cold H̄ without having to reach extremely cold plasma temperatures. The basic idea is similar to that proposed by Hessels et al (1998 Phys. Rev. A 57 1668) except that the order of the charge transfers is reversed. A beam of highly-excited (Rydb...

متن کاملFormation of Antihydrogen Rydberg atoms in strong magnetic field traps
It is shown that several features of antihydrogen production in nested Penning traps can be described with accurate and efficient Monte Carlo simulations. It is found that cold deeply-bound Rydberg states of antihydrogen (H̄ ) are produced in three-body capture in the ATRAP experiments and an additional formation mechanism -Rydberg charge transfer-, particular to the nested Penning trap geometry...

متن کاملDark Cloud Cores and Gravitational Decoupling from Turbulent Flows
We test the hypothesis that the starless cores may be gravitationally bound clouds supported largely by thermal pressure by comparing observed molecular line spectra to theoretical spectra produced by a simulation that includes hydrodynamics, radiative cooling, variable molecular abundance, and radiative transfer in a simple one-dimensional model. The results suggest that the starless cores can...
