Along its path from the hollow cathode region toward the anode, an electron may collide with a neutralatom/molecule to produce collisional ionization. The combined effect of neutralatom depletion and defocusing of the pump beam due to the intensity-dependent density of free electrons, significantly modifies the conversion characteristics and efficiency. In a neutralatom, the negatively-charged electrons balance out the positive charge of the protons. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In this case one can examine the specular reflection of a slow neutralatom from a solid state surface. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A minimum basis set is where only sufficient orbitals are used to contain all the electrons in the neutralatom. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. If a hole associates itself with a neutralatom, that atom loses an electron and becomes positive. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. However, since an electron is lost, an otherwise neutralatom becomes ionized.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In chemical terms, if a neutralatom loses one or more electrons, it has a net positive charge and is known as a cation. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This unit is defined as a twelfth of the mass of a free neutralatom of carbon-12, which is approximately. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Collisions with neutral atoms or molecules are neglected. To get the mass of the neutralatom, the mass of the missing electrons and their binding energies have to be added to the measured ionic mass. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The plasma is assumed to be isothermal and to consist of electrons and singly charged positive ions in a background of neutral atoms. Therefore, for energies larger than the excitation potential, the kinetics of a dilute electron gas interacting with neutral atoms is always described by (1). It is defined as one twelfth of the mass of an unbound neutralatom of carbon-12 in its nuclear and electronic ground state, and has a value of.
