Cold Fusion is caused by the fusion of femto-D2 with covelent electron in deeper orbit than n=1, at a few femto-meters from the nucleus.
The covelent electron between d-d shiled the coulomb repulsive force between d-d.
and transmutation with femto-D2 causes the increase of atomic number by 4. Thus charge of 2d=4, charge of d is 2, which indicates that d is constituted only by protons ans internal electron.
Therefore it is very important to find the evidence that femto-H2 exists because femto-H2 is constituted by two protons.
Evidence that Femto-H2 exists leads to the correct mechanism of Cold Fusion.pdf

Thus current nucleus model that nucleus is constituted by proton and neutron is proved to be incorrect.
and correct nucleus model is that nucleus is constituted only by proton and internal electron, and neutron ia a pair of proton and electron in deeper orbit than n=1.

The evidence that femto-H2 exists is the mass analysis of brown gas, which is generated by the transmutation of H2O by femto-H2 generated in positive metal which cause Cold Fusion
