A new means of measuring cold collisions

In the study, the scientists examined collisions that occur between the molecules. Collisions of atoms have been studied in the past, but atoms - according to classical physics - are spherical, while molecules have an elongated structure. The structure of a colliding body affects the way it will move after the collision. Will elongated molecules behave differently from spherical atoms? And is knowing their shape enough to predict the outcome of the collision? Illustration: pixabay.com.
