Weaker lines of lower energy go to excited states, and there are frequently (a)If `alpha`-decays of `._(92)U^(238)` is energetically allowed (i.e., the decay products have a total mass less than tha mass of `._(92)U^(238)`), what prevents `._(92)U^(238)` form decaying all at once? Why is its half life so large?
(b) The `alpha`-particle faces a Coulomb barrier. A neutron being unchanged faces no such barrier. Why does the nucleus `._(92)U^(238)` not decay Show that 238 U cannot spontaneously emit a proton.

What would be the mass and atomic number for this resulting nucleus after the decay? Solution – 238 92 U → 238-4 92-2 Th + 4 2 He → 234 90 Th + 4 2 He. Therefore, the resulting Thorium nucleus should have 234 mass number and 90 atomic number. Alpha Decay Equation. Alpha decay formula can be written in the following way – A Z X → A-4 Z-2 Y + 4 2 α

Fissile / Fertile Material Cross-sections Uranium 238. Comparison Feb 17, 2009 An explanation of the radioactive decay of Uranium into Thorium, and the emission of an alpha particle.

The 238 U decay chain contributes 6 electron anti-neutrinos per 238 U nucleus (1 per beta decay), resulting in a large detectable geoneutrino signal when decays occur within the Earth. The decay of 238 U to daughter isotopes is extensively used in radiometric dating, particularly for material older than ~ 1 million years.

The number of disintegration per second occur Nov 24, 2008 Alpha Particle Emission: In alpha particle emission, an unstable nuclide For example, the alpha decay of uranium-238 emits two gamma ray While 234U, 235U and 238U have essentially the same chemical and physical in Tables 2-2 and 2-3, all uranium isotopes primarily decay by alpha emission.

Uranium has three primary naturally occurring isotopes isotopeA form of an element that has the same number of protons but a different number of neutrons in the nucleus, giving it a different atomic mass. For example, uranium has thirty-seven different isotopes, including uranium-235 and uranium-238.: U-238, U-235 and U-234. An example is the natural decay chain of 238 U: Uranium-238 decays, through alpha-emission, with a half-life of 4.5 billion years to thorium-234; which decays, through beta-emission, with a half-life of 24 days to protactinium-234; which decays, through beta-emission, with a half-life of 1.2 minutes to uranium-234 Find the energy released in the alpha-decay? 238.050786 – (234.043583 + 4.002603) = 0.0046 u .
