Deflection of Alpha & Beta Radiation in an Electric & Magnetic Field
To explain how alpha and beta particles are deflected, the following two figures have been provided in my textbook but without any explanation for the intensity of the deflections shown:
I have two ...

Changing electromagnetic and strong coupling in tandem?
It has been widely said that if $\alpha$ were to increase by only a few percent, life would be impossible because of the lack of carbon production in stars--and if it is increased too much, ...

What is the emission spectra of electrons under the Zeeman/Stark effect?
As the Zeeman effect/Stark effect lead to a change in the energy levels of orbital electrons in relation to their spin, similar to hyperfine transitions, I was wondering what the emission spectra of ...

Is there any conversion mechanism of neutron radiation into electromagnetic radiation?
Charged radiation such as beta, alpha or even stray protons and nuclei as they are charged can loose their energy as photons. Can neutrons do this as well, even if they do not have any electric charge ...

Why does the binding energy per nucleon rise as the nucleon number rises, then go down again, with nuclei heavier than iron? [duplicate]
As the strong nuclear force is a short range force, and as it is way stronger than Coulomb force, Lumen Learning answered my question as follows:
“for low-mass nuclei, the nuclear attraction dominates ...

Is electric potential energy responsible for energy release in nuclear fission and nuclear potential energy in fusion? What if elec. force not exist?
It was my doubt and I thought it may be electric potential energy which is responsible for energy release in nuclear fission and by bombarding neutron we only provide energy to nucleons to cross ...

Why is the alpha particle in alpha decay considered to be in a potential well?
I understand that when modelling alpha decay, it is useful to consider the $\alpha$ particle as being preformed, in a region confined to the daughter nuclei. I also understand that the term $V_{0}$ ...

Why is residual strong force needed?
I was wondering why the residual force was needed to hold nucleons together? If the net charge resides on the surface and acts perpendicular to the surface (page I found, though not about nuclei), how ...

What would happen if the attractive force at work in the nucleus had been equal in magnitude to the repulsive electrostatic force between the protons?
I am just starting with radioactivity and I came upon this statement:
"Since the nucleus is stable, this means that there is some attractive force at work in the nucleus and that its magnitude ...

Why does a magnetic transition $\mathrm{M}(\ell)$ have approximately the same probability as an electric $\mathrm{E}(\ell+1)$ transition?
When discussing electromagnetic decays and multipolarity, B. Povh, et al.$^1$ state that the magnetic transition $\mathrm{M}(\ell)$ have approximately the same probability as an electric $\mathrm{E}(\...

Using an electric field to rip apart a nucleus
Can we use an electric field to rip apart a nucleus? . Let's take 3He which is a very stable isotope but unfortunately not commonly found. And let's assume we have placed an 3He inside a spherical box ...

Does nuclear binding energy concern nuclear force or EM force?
From my understanding, binding energy is the energy required to separate all nucleons in a nucleus an infinite distance away from each other. I cannot tell whether this ignored the effect of one of ...

Is spin-orbit coupling mass dependent?
When comparing spin-orbit coupling in the case of electrons and in the case of nucleons, do nuclear states exhibit a stronger level splitting compared to atomic states because the nucleons are more ...

Understanding interaction between two quarks
Two protons and two electrons repel each other as they have same charge. Protons and electrons attract each other since they are oppositely charged.
A single proton is made up of two up and one down ...

Calculating energies in Coulomb regime, is there an equivalent to the Fourier transform for free space?
In free space, one can find the energy decomposition of a wavefunction by using Fourier transform. Is there an equivalent common transformation to do this for a wavefunction in a Coulomb potential? ...
