We demonstrated the accurate prediction of a quasibound spectrum of a negative ion using a high-precision theoretical approach. We used ${\mathrm{La}}^{\ensuremath{-}}$ as a test case due to a recent experiment that measured energies of 11 resonances

The properties of atomic negative ions are to a large extent determined by electron-electron correlation which makes them an ideal testing ground for atomic many-body physics. In this paper, we present a detailed experimental and theoretical study of

The first direct experimental observation of an electric quadrupole ($\textit{E}$2) transition between bound states of an atomic negative ion has been made. The transition was observed in the negative ion of bismuth by resonant (1+1) photodetachment

The negative ion of lanthanum, La$^-$, has one of the richest bound state spectra observed for an atomic negative ion and has been proposed as a promising candidate for laser-cooling applications. In the present experiments, La$^-$ was investigated u

The electron affinity of thallium has been precisely measured using laser photodetachment threshold spectroscopy. The relative photodetachment cross section from the negative ion $^{205}\mathrm{Tl}^{\ensuremath{-}}$ was measured using a tunable infra

Binding energies of fine structure levels of the negative ion of gallium have been determined both experimentally and theoretically, resolving long-standing discrepancies for the electron affinity of gallium. The relative photodetachment cross sectio

Synopsis The electron affinity of thallium, Tl, has been measured using tunable infrared laser photodetachment threshold spectroscopy. The relative cross section for neutral atom production following photodetachment from Tl− was measured with a cro
