When we consider isotopic reactions, we are talking about isospin. Isospin is the most fundamental properties of matter. Charge emerges from isospin. When isotopes are changed through a LENR reaction, the character of matter that matters is isospin.
When we consider what isotopes react of don’t react, we are really considering what isospin is doing through the reaction. The LENR reaction causes the isospin of the nucleus to change. This should be impossible because of the conservation law dealing with isospin. So something is overriding the natural laws that govern the behavior of isospin. That factor is not a constant. This factor acts on isospin based on its strength. We cannot generalize how isotope transmutation will behave from one system to another because the strength of this elusive “LENR transmutation factor” is different from one system to another. This LENR transmutation factor is of course “magnetism”. Each system will produce magnetism in a unique way and that magnetism will be generated in a system specific range of strength, and because of this magnetic strength variability, each system will require a different isotope to function when the magnetism that is produced is weak. But the strength of magnetism is unlimited and some systems will not be constrained by the strength of the magnetism it can produce. So there is a continuum of LENR reaction transmutation characteristics form minimal (Rossi) to intermediate (DGT) to unlimited like LeClair. Magnetism imparts no kinetic energy into the transmutation reaction so the resultant isotope is stable meaning that it is not excited (radioactive). This magnetic transmutation process will find the most stable configuration for the resultant isotope. When the magnetic fields are strong, and the screening of charge is near complete, many combinations of protons and nuclei may become involved in the transmutation process and the resultant isotope will tend to form magic number based configurations.
