As discussed in Chapter 1, the radioactivity of heavy atoms, embodied in the three processes of α-, β- and γ-decay, were early indicators of nuclear activity. With the production of many species of nuclei in

RADIOACTIVE DECAY: understand radioactive decay. describe alpha, beta and gamma radiation? Atomic Theory and Radioactive Decay Natural background radiation exists all around us. This radiation consists of high energy particles or waves being emitted from a variety of materials. Radioac...
The order ${\\\mathcal O} (\\\alpha \\\alpha_s m_t^2 /M_W^2)$ corrections to the partial decay rate of $\\\Gamma (Zo b\\\bar b)$ are computed using the heavy top mass expansion. They are given by the absorptive part of the corresponding three-loop Z self-energy diagrams....

Alpha decay and spontaneous fission of the ground-state and the isomeric state of Md-247 were investigated with specific emphasis to identify the ground-state of the daughter nucleus Es-243. The decay studies were accompanied by measuring alpha-gamma coincidences. On the basis of the measured ...
The decay of No-255 was investigated by means of alpha-gamma spectroscopy. The isotope was produced in the reactions Pb-208(Ca-48, n)No-255,(209) Bi (Ca-48; 2n) Lr-255 (-->) (EC) No-255, and U-238 (Ne-22; 5n)No-255. Levels of the daughter nucleus Fm-251 were assigned ...
