A molecular beam is produced by allowing a gas at higher pressure to expand through a small orifice into a chamber at lower pressure to form a beam of particles ( atoms, free radicals, molecules or ions) moving at approximately equal velocities, with very few collisions between the particles. Molecular beam is useful for fabricating thin films in molecular beam epitaxy and artificial structures such as quantum wells, quantum wires, and quantum dots. Molecular beams have also been applied as crossed molecular beams. The molecules in the molecular beam can be manipulated by electrical fields and magnetic fields. Molecules can be decelerated in a Stark decelerator or in a Zeeman slower.

I put it in the tension testing machine, and clamped itthe clamp was good for 10,000,000 poundsbut it began to bend, so I had to quit Then Morey held it with a molecular beam, and I tried twisting it.
To achieve this acceleration, the LPS contains a state-of-the-art molecular beam epitaxy (MBE) facility to develop miniature lasers, optical amplifiers, and other components made out of gallium arsenide.
Using the molecular beam, she released gas particles into the plasma.
