Mass numbers of typical isotopes of Americium are 241-243. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N.Neutron number plus atomic number equals atomic mass number: N+Z=A.The difference between the neutron number and the atomic number is known as the neutron … Americium-241 decays mainly via alpha decay, with a weak gamma ray byproduct. The α-decay is shown as follows: + + + The α-decay energies are 5.486 MeV for 85% of the time (the one which is widely accepted for standard α-decay energy), 5.443 MeV for 13% of the time, and 5.388 MeV for the remaining 2%.
