With respect to this process, a "dollar" is the separation between states of prompt and delayed criticality. Tin appears to be the lightest element in which this process can be induced by gamma rays, and this process is spontaneous if the ratio Z squared over A is greater than or equal to forty-five. This process can be modeled by the six- or four-factor formula, both of which gives the effective (*) neutron multiplication factor. Reactors for this process are "poisoned" by the presence of elements like xenon. This process, which occurs in nuclei heavier than nickel-62, releases an amount of energy equal to the difference of product minus reactant binding energy. For 10 points, name this process by which a nucleus is split apart, often used on uranium-235.
