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 کاملPionic decay of L hypernuclei in a continuum shell model
The pionic decay of L hypernuclei has received attention in the past both from the experimental @1–7# and theoretical @8–22# points of view ~for a recent review see Ref. @23#!. It is well known that the mesonic decay is largely suppressed by Pauli blocking, although the consideration of proper pion distorted waves @13,16,20# weakens the effect of the Pauli blocking considerably. On the other ha...
متن کاملPionic decay of Λ Hypernuclei in a Continuum Shell Model
We evaluate pionic decay widths of Λ hypernuclei using a shell model for, both the nuclear bound and the continuum nucleon wave functions in the final state, and distorted waves for the outgoing pion. An excellent agreement with the recent KEK measurement of π −-decay widths of 12 Λ C and 28 Λ Si is found. Besides, results for 56 Λ Fe are consistent with the existing upper bound.
متن کاملDecay estimates of solutions to the IBq equation
In this paper we focus on the Cauchy problem for the generalized IBq equation with damped term in $n$-dimensional space. We establish the global existence and decay estimates of solution with $L^q(1leq qleq 2)$ initial value, provided that the initial value is suitably small. Moreover, we also show that the solution is asymptotic to the solution $u_L$ to the corresponding linear equa...
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...
