And I had to look this up. The most stable form of Nitrogen is N14, so I guess it normally has 7 neutrons and N9 is produced when N14 sheds 5 neutrons. Other isotopes are N13 (rare, short lived) and N15 (0.4% of all nitrogen, stable).

We wouldn't have all this N-14 around if that happened. They just break other stuff to see if n-9 appears briefly in the debris:
