31. This will make SNO + the largest experiment to study neutrinoless double beta decay . 32. The more neutron rich the fragment, the more energetic and faster the beta decay . 33. Calcium-48 is the lightest nuclide to undergo double beta decay . 34. Polonium's isotopes tend to decay with alpha or beta decay . 35. In that case, it could annihilate with another neutrino, allowing neutrinoless double beta decay . 36. The first decay processes to be discovered were alpha decay, beta decay , and gamma decay. 37. In 1930, Pauli considered the problem of beta decay . 38. "Ordinary " double beta decay results in the emission of two electrons and two antineutrinos. 39. Beta decay is when a neutron is transformed into a proton, electron and a neutrino.40. Many isotopes are theoretically expected to double beta decay .
