It is worth noting, there are slow neutrons and fast neutrons. Fast neutrons are only useful in fission for the splitting of atoms. What it appears the Nazis were attempting to achieve was fusion ,or the adding of neutrons and protons to Thorium 232 to transform it into Uranium 233. An element is defined by the number of Protons in it's nucleus.

Mar 31, 2021 The most stable isotope, 232Th, has a half-life of 14.05 billion years, An even number of either protons or neutrons generally increases

Alpha particles always have this same composition: two protons and two neutrons.

Thorium 232, which alone makes up nearly all natural thorium, is the most common isotope of thorium in the nature.This isotope has the longest half-life (1.4 x 10 10 years) of all isotopes with more than 83 protons.

Positron decay is the conversion of a proton into a neutron with the emission of a (c) thorium-232 decays and produces an alpha particle and a radium-228 Investigations aimed at the development of neutron and proton cross-section evaluations for Th-232 at intermediate energies in the range of 0 to 200 MeV are Several age determinations have been made by means of the Thorium-232 isotope. Its strongest spectral Uranium-238 contains 92 protons and 146 neutrons.
