31. A half-life of 0.89 ms was calculated : decays into by alpha decay . 32. The first decay processes to be discovered were alpha decay , beta decay, and gamma decay. 33. It does not work through fission like a nuclear reactor does, but through natural alpha decay . 34. The elements heavier than that have to shed weight to achieve stability, most usually as alpha decay . 35. It is also possible that 298 Fl can be synthesized by the alpha decay of a massive nucleus. 36. In contrast, actinides undergo multiple alpha decays , each with decay energy around 4-5 MeV. 37. Rutherford and Soddy were observing natural transmutation as a part of radioactive decay of the alpha decay type. 38. Calculations in a quantum tunneling model show that such superheavy nuclei would undergo alpha decay within microseconds or less. 39. Lighter astatine isotopes have quite high energies of alpha decay , which become lower as the nuclei become heavier. 40. All of these decay only through alpha decay , although some unknown bohrium isotopes are predicted to undergo spontaneous fission.
