For example, no one knows whether electrons in the ground state tend to pair up so that they have opposite spins, as they do in atoms.
We show that a confined model to the three-body molecule reproduces the ground state curve as calculated by Kolos, Szalewics and Monkhorst [6] with a precision up to the 4-th digit and a precision in the representation of the binding energy up to the 5-th digit.
The researchers suggest that further investigations, experimentally and theoretically, are required to ultimately determine the true identity of the ground state of the material.
It is thought to be the single strongest emission from newly forming stars; hydrogen atoms radiate this ultraviolet light when an electron falls from the first excited state to the ground state.

Exposing such a confined particle to a pulse of laser light of precisely the right wavelength and duration can readily kick it into an excited energy state; a second laser pulse can restore it to its ground state.
Critically, the unprecedented resonant frequencies of diamond cantilevers allow the possibility of cooling cantilever devices down to the ground state.

A "pump" laser was used to excite barium atoms from their ground state to a higher energy level just before the atoms entered the 1-millimeter gap between the two curved mirrors (see diagram).
The resulting quantitative model not only accounts for all known data on ground state cold cesium atom collisions, but also accurately predicted locations for a number of resonances in the Stanford experiment prior to measurements having been made.
