Using laser technology to measure the rotational cooling of molecular ions colliding with electrons - Phys.org

When it is free in cold space, a molecule will spontaneously cool down by slowing its rotation and losing rotational energy in quantum transitions. Physicists have shown that this rotational cooling process can be accelerated, slowed down and even inverted by…
