41. Most of the other isotopes of californium decay to isotopes of curium ( atomic number 96 ) via alpha decay . 42. Francium-221 then decays into astatine-217 by alpha decay ( 6.457 MeV decay energy ). 43. The chain begins with the alpha decay of 232 Th to 228 Ra, and terminates at stable 208 Pb. 44. Theoretical estimates of alpha decay half-lives of isotopes of nihonium are in good agreement with the experimental data. 45. They were able to detect alpha decays from fermium isotopes, assigned as descendants of the decay of 262 Hs. 46. Why doesn't " Characteristics ", " Nuclear " section describe the alpha decay of Pu-238? 47. Since alpha particles are the same as a helium nucleus, can one produce helium by alpha decay of Uranium? 48. A Spanish edition from Alpha Decay and a French edition from Au Diable Vauvert will be published in January 2014. 49. This is useful in considering the barrier tunnelling mechanism involved with alpha decay and in deriving the Geiger Nuttall law. 50. However, 154 Dy decays primarily by alpha decay , and 152 Dy and 159 Dy decay primarily by electron capture.
