Geometric phases causing lifetime modifications of metastable states of hydrogen
Martin-Isbjörn Trappe, Peter Augenstein, Maarten DeKieviet +2
Externally applied electromagnetic fields in general have an influence on the width of atomic spectral lines. The decay rates of atomic states can also be affected by the geometry…
Metastable states of hydrogen: their geometric phases and flux densities
T. Gasenzer, O. Nachtmann, M. -I. Trappe
We discuss the geometric phases and flux densities for the metastable states of hydrogen with principal quantum number n=2 being subjected to adiabatically varying external electri…
Longitudinal Atomic Beam Spin Echo Experiments: A possible way to study Parity Violation in Hydrogen
M. DeKieviet, T. Gasenzer, O. Nachtmann +1
We discuss the propagation of hydrogen atoms in static electric and magnetic fields in a longitudinal atomic beam spin echo (lABSE) apparatus. Depending on the choice of the extern…
Parity Violation in Hydrogen and Longitudinal Atomic Beam Spin Echo I
T. Bergmann, T. Gasenzer, M. DeKieviet +2
We discuss the propagation of hydrogen atoms in static electric and magnetic fields in a longitudinal atomic beam spin echo (lABSE) apparatus. There the atoms acquire geometric (Be…
Metastable states, the adiabatic theorem and parity violating geometric phases II
Timo Bergmann, Thomas Gasenzer, Otto Nachtmann
We discuss and calculate parity conserving (PC) and parity violating (PV) geometric phases for the metastable 2S states of hydrogen and deuterium. The atoms are supposed to be subj…
Metastable states, the adiabatic theorem and parity violating geometric phases I
Timo Bergmann, Thomas Gasenzer, Otto Nachtmann
A system of metastable plus unstable states is discussed. The mass matrix governing the time development of the system is supposed to vary slowly with time. The adiabatic limit for…
