Q:
If H+H is transmuted to He, and H only has a proton and an electron, where do the neutrons come from that are prepresent in He? Thank you for your help! Lance

A:

Dear Lance,

The answer is no for the reason you mentioned.   You need two additional neutrons.  A two proton system is not stable.  You need the extra binding energy provided by the two neutrons.
