In addition the Carbon nucleus has 2 binding negative electrons, the 
Nitrogen has 2 H nuclii added and a es electron. The Oxygen has 
a He nucleus instead of the 2 H nuc 
If now after collision son a's wift a particle the Nitrogen nucleus loses

The general conclusion to be dra pies all this extremely interest-

A most significant point is this: that the Hydrogen nucleus of charge
