Franck–Condon factors and observed band strength distribution in the vibrational structure of the Ag2 D-X band system [PDF]

Journal of the Serbian Chemical Society, 2010
TPotential curves for the X1Sg+ and D1Su+ states of three diatomic silver isotopomers, 107Ag2, 107Ag109Ag and 109Ag2, were determined from the best available molecular constants by the Rydberg–Klein–Rees method.

Spin-Interaction Effects for Ultralong-range Rydberg Molecules in a Magnetic Field

, 2018
We investigate the fine and spin structure of ultralong-range Rydberg molecules exposed to a homogeneous magnetic field. Each molecule consists of a $^{87}$Rb Rydberg atom whose outer electron interacts via spin-dependent $s$- and p-wave scattering with ...

Antiprotonic helium atomcules

EPJ Web of Conferences, 2012
About 3% of antiprotons () stopped in helium are long-lived with microsecond lifetimes, against picoseconds in all other materials. This unusual longevity has been ascribed to the trapping of on metastable bound states in He+ helium atom-molecules thus ...

Observation of mixed singlet-triplet Rb$_2$ Rydberg molecules

, 2016
We present high-resolution spectroscopy of Rb$_\text{2}$ ultralong-range Rydberg molecules bound by mixed singlet-triplet electron-neutral atom scattering.

Ionization energy of Rb_{2} by electric field ionization of molecular Rydberg states

Physical Review Research
We report the measurement of the ionization energy of the ^{85}Rb_{2} molecule through resonantly enhanced two-photon ionization in a supersonic beam. The first photon excites the X^{1}Σ_{g}^{+}(v_{X}=0)→B^{1}Π_{u}(v_{B}=2) transition, while the second ...

Vibrational-State-Dependent Decay of the CO C(1s) Excitation

, 1995
Molecular ionization and ionic fragmentation of core excited CO valence and Rydberg states are studied by partial-ion-yield spectroscopy at vibrational resolution.

Anomalies in radiation-collisional kinetics of Rydberg atoms induced by the effects of dynamical chaos and the double Stark resonance

, 2013
Radiative and collisional constants of excited atoms contain the matrix elements of the dipole transitions and when they are blocked one can expect occurring a number of interesting phenomena in radiation-collisional kinetics.

Many-body physics with ultracold plasmas: quenched randomness and localization

New Journal of Physics, 2019
The exploration of large-scale many-body phenomena in quantum materials has produced many important experimental discoveries, including novel states of entanglement, topology and quantum order as found for example in quantum spin ices, topological ...

Ultrafast dynamics of neutral superexcited Oxygen: A direct measurement of the competition between autoionization and predissociation

, 2012
Using ultrafast extreme ultraviolet pulses, we performed a direct measurement of the relaxation dynamics of neutral superexcited states corresponding to the nl\sigma_g(c^4\Sigma_u^-) Rydberg series of O_2. An XUV attosecond pulse train was used to create
