A Possible Design of the NLC e Source
... such a device could deal with the requirements of NLC. Here we restrict ourselves to the poesibility of increasing the acceptance. The acceptance of the positron system could be considerably increased by a pre-damping ring [l]. Such a ring would be located between the positron accelerator and the ma ...

... Now, let us conduct a second experiment: keeping both slits open, we dim the source of light, until the emitted photons strike the screen practically one by one. In this case, the interference must diminish, and the fringes should disappear. When conducting the experiment, we find the following: 1. ...

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).
