Molecular physics: Recombination cool and fast
Benjamin J. McCall1
Abstract
Molecular physicists and astrophysicists alike would like to know how fast the H3+ molecular ion recombines with electrons. Fast, seems to be the answer — with an awkward consequence for the astrophysicists.
Every schoolchild knows that, like opposing poles of a magnet, opposite charges attract. But what happens when charged bodies are small enough that the rules of quantum mechanics come to bear, for instance when an electron and a positively charged molecule attract?
