My thought on the E-CAT.

. 
The reaction produces 11% Fe, 10% Cu and some Zn.
⁶²Ni to ⁶³Cu (70%) and ⁶⁴NI to ⁶⁵Cu (30%). ⁶⁴Cu decays to ⁶⁴Zn as well as ⁶⁴Ni. Proton-induced reactions on nickel.  Chain reaction nickel + proton  + gamma yields iron + double proton emission?  Effect of electrons migrating from nickel lattice to hydrogen atoms, the Beryllium shielding on the reaction and Mössbauer effect.
