Circular RABBITT goes under threshold
Vladislav V. Serov, Jia-Bao Ji, Meng Han +3
We introduce circular under-threshold RABBITT (cuRABBITT) as a new interferometric method to probe discrete electronic excitations in atoms with attosecond resolution. By combining…
Crossover between the zeptosecond and attosecond physics
T. Nandi, Yash Kumar, Adya P. Mishra +7
Nuclear orbiting resonances have been revealed at the sub-barrier energies as an atomic phenomenon by means of x-ray spectroscopy experiments. This interpretation is supported by s…
Continuous rainbow RABBITT investigation of resonant states in He and H
Vladislav Serov, Anatoli Kheifets
We employ Reconstruction of Attosecond Beating By Interference of Two-photon Transitions with an advanced energy resolution (rainbow RABBITT) to resolve under-threshold discrete ex…
Double--hole resonances in single photoionization of He-like B ions
A. Müller, P. -M. Hillenbrand, S. -X. Wang +8
Within a joint experimental and theoretical research project, single photoionization of He-like B ions was investigated in the energy range from approximately 250 to 1200~eV…
