Based on the relativistic quark model and infinitesimally shifted Gaussian basis function method, we investigate mass spectra of double bottom baryons systematically. In $\rho$-mode which appears lower in energy than other excited modes, obtain allowed quantum states perform a systematic study $\Xi_{bb}$ $\Omega_{bb}$ families. We analyze root mean square radii radial probability density distri...

A new database and viewer for mass spectra resulting from collision processes is presented that follows the standards of Virtual Atomic Molecular Data Centre (VAMDC). focus was placed on machine read write access, as well ease use. In a browser-based viewer, all parameters related to given measurement can be shown. The program additionally enables direct comparison between two spectra, either b...

Three electronic absorption systems for C5 at 511, 445, and 232 nm and one for C6, C8, and C9 centered at 228, 259, and 288 nm have been observed in the gas phase. The C5 chain was produced in both discharge and ablation sources and detected using resonant two-color two-photon ionization spectroscopy involving 10.5 eV photons. The decay of the excited singlet electronic states indicates fast in...
