Justifying that the gold nucleus is at rest in a Rutherford experiment
This is an example on the Rutherford Experiment from Young and Freedman's University Physics.
In the last paragraph of the solution the book states that it is valid to assume that the gold nucleus ...

Why does classical physics not predict particles in the double-slit experiment to land in just two different locations?
I stopped being able to understand the double-slit experiment way before any of the interference and associated "quantum weirdness" came into play. I get that one needs to approach this ...

Numerically Stable form of Scattering Angle
I'm working through the problems in Chapter 3 of the 3rd edition of Goldstein's Classical Mechanics and I'm stuck on Derivation 4. This problem asks the reader to rewrite the scattering angle

Rainbow Scattering Potential Function
I am studying the 3rd edition of Goldstein's Classical Mechanics and in the discussion of scattering in a central field, the author mentions (but does not give the formula for) the following potential ...

Scattering Differential Cross Section Laboratory Frame
Let the differential cross section of a scattering experiment given by $\frac{\text{d}\sigma_{c}}{\text{d}\Omega_{c}}(\vartheta_{c})$, where $\vartheta_{c}$ describes the scattering angle in the ...

Equation for the trajectory of a positively charged particle fired towards an atomic nucleus
I'm interested in finding (or rather the mathematical approach to finding) an equation for the trajectory of a particle with charge $+q\space$ fired toward a stationary nucleus, i.e. the 'height' ($y$...

What accounts for the difference in factor of 4 between quantum cross section and classical cross section?
In classical mechanics, we could calculate the total cross section of scattering from hard sphere to be $$\pi a^2$$
where $a$ is the radius of sphere.
Recently in quantum mechanics we calculated the ...

Can’t find the right impact parameter - flux of particles scattered by surface of revolution [closed]
I’ll be so happy to understand what am I doing wrong.
There is no potential in the question so I assumed this is solvable by geometry alone. The question ask for the impact parameter while
$$\rho=\...

Has the double slit experiment with classical projectiles ever been performed?
I was wondering if the double slit experiment with mascroscopic objects has ever been tried. In any course of quantum mechanics, a way to introduce quantum effects is to introduce the double slit ...

Physical Intuition of Inelastic Mean Free Path
The inelastic mean free path (IMFP) is a quasi-universal curve which describes how far a beam of electrons will travel through a material before scattering inelastically. I have been searching for ...

Classical motion in delta potential
The question about classical motion in delta potential may seem artificial, but it makes sense if you try to calculate the propagator for particle in delta-potential, because you usually need to know ...

Reference request: Scattering from action
Consider a separable solution to a Hamilton-Jacobi equation of an $n$-dimensional autonomous system of the form
$$W(\alpha_1,...,\alpha_n,x^1,...,x^n) = \sum_j \int_0^{x^j} w^j(\alpha_1,...,\alpha_n,x'...

Why does the scattering cross section equal to the sum over all differential cross section; including the incident angle?
According to Beer Lambert's law, the intensity of light passing through a homogeneous medium diminishes at a rate proportional to the incident intensity; i.e.
$$
\frac{dI(s)}{ds} = -I(s)\sigma\, ,
$$
