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 ...
Level matrix, 16N beta decay, and the 12C( alpha, gamma )16O reaction The level matrix corresponding to the K-matrix parametrization of a resonant nuclear reaction is derived and applied to the spectrum of alpha particles emitted following N-16 beta decay. The parametrized spectrum is fitted...
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, alpha g... F Azaiez,S Fortier,S Gales,... 被引量: 1发表: 1985年 The γ-decay of the 1g92 and 2p inner-hole states in 111S...
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...
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 ...
The αγ linear polarization correlation coefficients of the 271 keV and 401 keV γ-transitions in the decay of 219Rn have been determined to be B 2 = 0.029±0.011, B 4 = 0.0147±0.0042; B 2 = -0.093 ± 0.0084, B 4 = 0.0130±0.0034, respectively. The 130 keV γ-271 keV γ ...
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....

We are studying the beta-delayed proton decay of Ne-17 with the goal of determining the E2 part of the C-12(alpha,gamma)O-16 cross section at energies relevant to helium burning in stars. We have determined branching ratios for proton and alpha-decay for states in F-17 from 8.08 to ...
