Noun
(physics) the lowest energy state of an atom or other particle
Source: WordNetIn this case, the particle formed has correspondingly less energy, whereas the product nucleus passes into the ground state with emission of the quantity of energy saved as gamma radiation. Walther Bothe
I learned, practically in my cradle (actually from Bill McMillan's thesis), that the ground state wave function of a system of bosons should necessarily be real and positive, a fact which made his early Monte Carlo simulations infinitely easier. Philip Warren Anderson
See, everybody looks at the world from his own point of view. I call it the ground state of the resting mind. And your brain does the same thing, left alone it returns to and thinks about what it's really interested in. Charles Sheffield
After one of these decays the resultant nucleus may be left in an excited state, and in this case it decays to its ground state by emitting high energy photons (gamma decay). Source: Internet
A singly charged vortex ( ) is in the ground state, with its energy given by : where is the farthest distance from the vortex considered. Source: Internet
Another factor is that the emission of fluorescence frequently leaves a fluorophore in a higher vibrational level of the ground state. Source: Internet
