The Nickel 58 to nickel 62 change does not create low energy fusion. It may create radiation. Nickel at temperatures between 250 and 600 degree have the best energetic state. Nickel with excess nickel 63 isotope is required to create lenr. A three layer core is required: The inner layer based on electrical current; an fuel layer with nickel and 1% Nickel 63 isotope with the nickel at 20 microns and 30% lithium; and a outside layer called the monazite layer used to transfer heat.
