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 their ground or excited states through nuclear reactions such decays have been ...

Fig. 3. Positron decay. An example of this decay occurs in sodium-22 nucleus that decays into neon-22 nucleus with the emission of beta-plus particle. 1.2.3 Gamma decay In gamma decay, the parent isotope emits a gamma photon that has no charge (Fig. 4). The parent isotope is in exc...
Gamma-Decay of the 1Gsub(9/2) and 2P Inner-Hole States in sup 111 Sn Via the sup 112 Sn( sup 3 He) Reaction at 32 MeV The gamma-decay of the deeply-bound hole states in sup 111 Sn has been investigated at 32 MeV incident energy by means of the sup 112 Sn( sup 3 He, alp...
Beta diversity, rather than alpha diversity per se, appears to be the main driver of spatial differences in gamma diversity between temperate and tropical regions. Conversely, we observed high plant alpha diversity at fine grains but relatively low alpha diversity at coarse grains in many temperate...

Three Types of Radiation: Rutherford identified three types of radiation using an electric field. 1) Positive alpha particles were attracted to the negative plate. 2) Negative beta particles were attracted to the positive plate. 3) Neutral gamma rays did not move towards any plate....

The level matrix corresponding to the {ital scrK}-matrix parametrization of a resonant nuclear reaction is derived and applied to the spectrum of {alpha} particles emitted following {sup 16}N {beta} decay. The parametrized spectrum is fitted to data simultaneously with the {ital E}1 capture ...
We present a new, simplified analysis of the low-energy electron-positron interaction, and use the resulting effective theory to calculate the binding effects that contribute to the decay rate, Gamma, of orthopositronium, through Order(alpha^2 Gamma). We express the total decay rate in terms ...
