state

 [stāt]
condition or situation.
alpha state the state of relaxation and peaceful awakefulness associated with prominent alpha brain wave activity.
anxiety state the condition of experiencing undue anxiety, as in anxiety disorders.
excited state the condition of a nucleus, atom, or molecule produced by the addition of energy to the system as the result of absorption of photons or of inelastic collisions with other particles or systems.
ground state the condition of lowest energy of a nucleus, atom, or molecule.
persistent vegetative state a condition of profound nonresponsiveness in the wakeful state caused by brain damage at whatever level and characterized by a nonfunctioning cerebral cortex, the absence of any discernible adaptive response to the external environment, akinesia, mutism, and inability to signal; the electroencephalogram may be isoelectric or show abnormal activity. Vegetative states raise ethical questions regarding appropriate care, use of resources, and allowing a patient to die.
refractory state a condition of subnormal excitability of muscle and nerve following excitation.
resting state the physiologic condition achieved by complete bed rest for at least 1 hour.
steady state dynamic equilibrium.

ground state

the normal, inactivated state of an atom from which, on activation, the singlet, triplet, and other excited states are derived.

ground state

1 the lowest energy level of a physical system. See also fatigue state.
2 the stable form of an atom or molecule.

ground state

(grownd stāt)
The normal, inactivated state of an atom from which, on activation, the singlet, triplet, and other excited states are derived.

ground state

the condition of a molecule when at its lowest energy level.

Hence, the outer shell of these two nuclear states consists of three identical fermions which make the required ground state.
baryon is the ground state of the three sss quarks and each of the baryons of the decuplet has an antisymmetric space-spin wave function.
of the ground state of the A = 31 nuclei displayed in the first line of table 1.
Thus, in spite of being a part of the decuplet whose members have space-spin antisymmetric states, these three baryons are the ground state of the uuu, ddd and sss quarks, respectively.
where [[absolute value of [PSI][n]> is any ground state wavefunction (generated by an arbitrary potential), that is, n is a ground state density belonging to an arbitrary system.
The ground state densities in (4) and (5) are called pure-state V-representable because they are the densities of the (possible degenerate) ground state of the Hamiltonian with some local potential v(r).
Then the many-body ground state wavefunction can be decomposed into single particle orbitals
In plain words, the trick is in realizing that the ground state energy can be found by minimizing the energy functional (4) and in rewriting this functional into the form (9), which shows that the interacting system can be treated as a noninteracting one with a special potential.
Fplf[alpha]] is the electronic optical transition matrix element between the ground state labeled by Fplf[alpha] and the exc ited state labeled by F'p'[beta].
The theory which underlies our calculation of the spectrum involves three major pieces: the ground state wavefunctions, the excited state wavefunctions and the molecular Rabi matrix which gives the optical coupling between them.
The first piece is the ground state wavefunction \[[PSI].
The molecular Rabi matrix elements depend on the excited rovibrational-hyperfine state quantum numbers, F'p'[beta]vJ', and the ground state hyperfine levels [f.
