Is beta decay spontaneous? What is the difference between alpha, beta, and gamma decay? What is emitted from the nucleus during beta decay? Why doesn't atomic mass increase in beta minus decay? What happens during alpha decay? What is the source of the electrons produced in beta decay?
What is emitted from the nucleus during beta decay? What is the alpha decay of iridium-174? How radioactive is nihonium? What makes a radioactive decay chain end? What are radioactive rocks? Is carbon-14 radioactive? What type of radioactive decay results in uranium-238 becoming thorium-23...
When he did this, he was able to detect electrons being emitted from the surface. This was Einstein's explanation: If the energy in light comes in bundles, then one can think of light as containing tiny lumps, or photons. When these photons strike a metal surface, they act like billiard...
single photon emission computed tomography (SPECT) is still the predominant technology worldwide, due to the easy availability ofγ-emitter radionuclides and the low cost of SPECT camera compared to PET scanner [4]. Therefore, the production of new γ-...

During their travel towards Earth, the emitted gamma-rays suffer from absorption by the extragalactic background light (EBL). The density of the EBL is not very well constrained by direct or indirect measurement which leads to uncertainties on the intrinsic spectrum of the sources. High-quality ...
Radioisotopes, or radionuclides, are unstable forms of elemental matter either man-made or found in nature. They all undergo a spontaneous process of radioactive decay through the emission of alpha and beta particles, gamma rays, and more. All of the elements on the periodic table with atomic ...
emitted inbeta decay have a continuousrather than a discrete spectrumthat appeared to contradict conservation of energy, under the then-current assumption that beta decay is the simple emission of an electron from a nucleus. When this was first observed,it appeared to threaten the surv...

With respect to hot, deformed systems it is argued that the discrepancy which exists between the measured and calculated asymmetry of the GDR γ-rays emitted in the fusion-fission process of hot actinide nuclei, might well be due to γ-emission during the saddle-to-scission stage of the ...
