neutral atom

neutral atom

[′nü·trəl ′ad·əm]
(atomic physics)
An atom in which the number of electrons that surround the nucleus is equal to the number of protons in the nucleus, so that there is no net electric charge.

During its science investigation, IBEX will use a pair of energetic neutral atom "cameras" to image interactions between the million mile-per-hour solar wind continually blown out by the Sun and the low-density material between the stars, known as the interstellar medium -- interactions never before imaged.
Scientists at NIST have demonstrated a novel source of atom flux that can provide one, and only one, atom essentially whenever it is needed--the first time such control over neutral atom delivery has been achieved.
