According to the Alpha-extended
model of the atom (1) heavier elements are made
from lighter elements by low energy transmutations
(Cold Fusion).
Vice versa, lighter elements can be produced by Cold
Fission of heavier elements: Cold Fusion and Cold
Fission are complementary and reversible processes.
In this paper I shall discuss the results of one experiment
of Cold Fusion and one experiment of Cold Fission.
