Explore: Decay Schemes (radioactivity)

decays very quickly to the ground state of 60Ni, via two gamma decays. All known decay schemes can be found in the Table of Isotopes., Nickel is to the right

emitted by the radioactive decay of an atomic nucleus, known as beta decay. There are two forms of beta decay, β− decay and β+ decay, which produce electrons

radioactive decay meant that this heat had been continually replenished. George Darwin and John Joly were the first to point this out, in 1903. Radioactivity, which

{\displaystyle _{e}} Since this single emitted neutrino carries the entire decay energy, it has this single characteristic energy. Similarly, the momentum

radioactive decay constant, the probability that an atom will decay per year, is the solid foundation of the common measurement of radioactivity. The accuracy
