The Theory of Alpha Decay
One of the relatively simple physical processes that can be described successfully in the framework of introductory quantum theory is alpha decay. In this process, two protons and two neutrons out of a relatively large nucleus dissociate from the rest of the nucleus, form a separate subsystem and subsequently depart. In its full complexity, this process is not be describable, however a reasonab...
متن کاملQuantum Mechanics of Alpha Decay
Quantum mechanical basis for the Geiger-Nuttal Law. Determination of the half-lives of several species in the Uranium, Thorium and Actinium series through the use of a scintillator, solid-state detector and coincidence circuitry. The half-lives of Po, Rn and Po are determined at 181 ± 5 s, 4.49 ± .01 days and 163 ± 1 μs, respectively. Verification of the theoretical relationship between half-li...
متن کاملThe nuclear radius from alpha decay
2014 Nuclear radii for mass numbers between A = 140 and 252 have been computed from 121 alpha decays between ground states of even-even nuclei. We use for that the two-body solution for the square well potential that we gave recently. The computed radii obey the A 1/3 law and they are consistent with the precise radii obtained from electron scattering. These two sets of radii show structures wh...
متن کاملSimple relation for alpha decay half-lives.
The experimental values of log&pT, yp(sec) plotted vs Zz /QQ are shown to fall on a nearly universal straight line with log, oT, ~z(sec)=(9. 54Z~. /1/Q ) —51.37, where Zz is the charge number of the daughter nucleus and Q is expressed in units of MeV. This behavior also numerically comes out of the semiclassical WKB calculation of the barrier penetration factor. The fine structure in the ratio ...
متن کاملAlpha decay of 0 excited states
The one-level B-matrix approach is used to calculate alpha decay widths for several low-lying 0+, 2+, and 4+ excited states of the 0 nucleus, The interior wave functions are calculated within the ZBM (pqy2, d5rq, sq12) shell-model space with various effective interactions. The exterior wave functions are calculated from an n+ C folding model potential obtained with the M3Y interaction. A new me...
