World's First Success in Amplification of Atomic Waves
The "manipulation of quantum fields" research team (research director Akira Shimizu, Associate Professor of the University of Tokyo) in the CREST (Core Research for Evolutional Science and Technology) project of the Japan Science and Technology Corporation (JST) succeeded for the first time in the world in the amplification of atomic waves indispensable for everlastig generation of the atomic wave laser. This research result was published in the U.S. science journal "Science" issued on December 17, last year.
The atom is not only a particle, but also has the nature of waves, and an atomic wave laser which matches phases is capable of micro-processing at a nanometer-scale and is expected to find wide applications.
Since the BEC phenomenon (Bose-Einstein condensation) in which the mass of about 1 million individual of gas atoms has the same energy condition under a very low temperature and behaves as if it were a single atom was artificially realized in the U.S. in 1995, the research of the atomic wave laser which utilizes atoms in the BEC condition has been developed.
The "manipulation of quantum fields" research team experimentally made a new matter-wave amplifier and tested it with gas atoms of rubidium. As a result, they succeeded in amplifying atomic waves for the first time ever and verified that the atomic waves increased by about 10 times.
With an originally developed interferometer, they also verified that the amplified atomic waves are coherent ones which matches the phases.
I hope it helps!

The reason that you could not find it is because there is no such thing. Oxygen has an atomic mass of 16, 17, or 18, an atomic number of 8, and a valence of -2.

What you might be looking for is an aspect of spectroscopy known as "persistant lines". A beam of sunlight creates a rainbow if it passes through a prisim. This does not happen if a neon light is used. The prisim generates several narrow bands of red light, spaced in a particular pattern. The reason this happens is that electrons occupy discrete energy states. When energized inside the neon tube, the electrons in the neon atoms jump into higher atomic orbitals. These orbitals are fixed, rather like the orbits of the planets. However, this is an atrificial situation and the electrons soon fall back into their regular orbits. However, the electron generates a photon of light equal to the difference in the two energy states. The energy of the photon is based on its wavelength, and all the photons generated for a particular energy shift will have the same wavelength. This is what a particular band of red light represents. All elements have unique patterns of colored light bands when their atoms are energized.
During the late 19th century many new elements were discovered by looking at the spectra of materials and finding bands which had not been seen before. I suppose it was like finding new stars and planets. The "rare earth" elements like Erbium and Praseodynmium are so chemically similar, it was difficult to separate them. However, spectrographic analysis of their oxides ("earths") suggested there was an undiscovered form of matter present. This led to further reduction and eventually the pure metals were isolated.

I'm sure you misheard 'weight' for 'wave' in which case, you probably have your info already. I'm quite sure there's no such thing as an atomic wave.

Are you looking for the waveLENGTH of an oxygen atom? Try looking up "De Broglie wavelength oxygen".

I think either you have read a typo or you have misheard something - while I am no scientist I believe that there is no such thing.
