... Are the interactions important? In the dilute gaseous atomic clouds in the traps, the interactions are incomparably weaker than in liquid helium. That permits to develop a perturbative treatment and to study in a controlled manner many particle phenomena difficult to attack in HeII. Several roles o ...

How many decays would you need to be certain to have two significant digits? For 10, 20, 30, 40 and 50 times the middle values were (in ms) 172, 462, 426, 525, and 489 so we ar ...

Finally, the observed probability of choosing to defect is given by |ϕDD|2 +|ϕCD|2. The quantum strategy Ut can b ...

Hydrogen atom



A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the elemental (baryonic) mass of the universe.In everyday life on Earth, isolated hydrogen atoms (usually called ""atomic hydrogen"" or, more precisely, ""monatomic hydrogen"") are extremely rare. Instead, hydrogen tends to combine with other atoms in compounds, or with itself to form ordinary (diatomic) hydrogen gas, H2. ""Atomic hydrogen"" and ""hydrogen atom"" in ordinary English use have overlapping, yet distinct, meanings. For example, a water molecule contains two hydrogen atoms, but does not contain atomic hydrogen (which would refer to isolated hydrogen atoms).
