Largest size for a monochromatic beam of X-rays is 1-5 mm.

Using an atomic paddle, a slow monochromatic beam of ground state helium was produced.

Unfortunately a monochromatic beam is of only limited use for spectroscopy unless it is tunable.

Shigubov's work has shown the theoretical possibility of building a so-called neutrino laser, or 'naser,' which could emit a monochromatic corpuscular beam.

For gyros, in principle any material that can be used to generate monochromatic light beams is applicable.

It wasn't until the development of high pressure nozzle sources capable of producing intense and strongly monochromatic beams in the 1970s that HAS gained popularity for probing surface structure.

Neutron diffraction is an excellent method for structure determination, although it has been difficult to obtain intense, monochromatic beams of neutrons in sufficient quantities.

A monochromatic beam of high-energy neutrinos sometimes employed for interplanetary communication thanks to its extremely small divergence angle.

These cells converted 850 nm light to electrical power with an efficiency of 53% - the highest efficiency reported at the time produced for a cell irradiated with a monochromatic beam.

Neutron velocity selectors are commonly used in neutron research facility to produce a monochromatic beam of neutrons.
