Testing the hypothesis: If cold fusion is taking place, we would expect elevated levels of helium-4 in the palladium rod.

Testing the idea of cold fusion (1 of 6)
Testing the hypothesis: If cold fusion is taking place, then we would expect to see heat generated.
Testing the idea of cold fusion (2 of 6)
Testing the hypothesis: If cold fusion is taking place, we would also expect to neutrons or helium-4 generated.
Testing the idea of cold fusion (3 of 6)
Pons' neutron results didn't agree with his heat measurements, with Jones' neutron results, or with established nuclear theory, which suggested no fusion should be occurring at all!
Testing the idea of cold fusion (4 of 6)
Testing the hypothesis: Could cold fusion really be taking place, or had Pons and Fleischmann made a mistake?
