Because the deuterons (heavy hydrogen) in heavy water already have neutrons,
whereas ordinary (light) water hydrogen (proton) doesn't.
The difference is enormous: 0.00053 b for deuterons vs. 0.332 b for protons
(thermal neutron abs. x-section)

	Why does light water absorb more neutrons than heavy water?
