Purcell modification of Auger and interatomic Coulombic decay
Janine Franz, Stefan Yoshi Buhmann
An excited two-atom system can decay via different competing relaxation processes. If the excess energy is sufficiently high the system may not only relax via spontaneous emission…
Spontaneous Electron Emission Versus Dissociation in Internally Hot Silver Dimer Anions
Patryk Jasik, Jan Franz, Dariusz Kędziera +3
Referring to a recent experiment, we theoretically study the process of a two-channel decay of the diatomic silver anion (Ag), namely the spontaneous electron ejection giving…
Rotational state-changing collisions of CH and CN anions with He under interstellar and cold ion trap conditions: a computational comparison
Jan Franz, Barry Mant, Lola González-Sánchez +2
We present an extensive range of quantum calculations for the state-changing rotational dynamics involving two simple molecular anions which are expected to play some role in evolu…
CAST constraints on the axion-electron coupling
K. Barth, A. Belov, B. Beltran +53
In non-hadronic axion models, which have a tree-level axion-electron interaction, the Sun produces a strong axion flux by bremsstrahlung, Compton scattering, and axio-recombination…
Search for 14.4 keV solar axions emitted in the M1-transition of 57Fe nuclei with CAST
CAST Collaboration, S. Andriamonje, S. Aune +58
We have searched for 14.4 keV solar axions or more general axion-like particles (ALPs), that may be emitted in the M1 nuclear transition of 57Fe, by using the axion-to-photon conve…
Search for solar axion emission from 7Li and D(p,gamma)3He nuclear decays with the CAST gamma-ray calorimeter
CAST Collaboration, S. Andriamonje, S. Aune +58
We present the results of a search for a high-energy axion emission signal from 7Li (0.478 MeV) and D(p,gamma)3He (5.5 MeV) nuclear transitions using a low-background gamma-ray cal…
