B Angular distribution to energy distribution

AI Thread Summary
To transform angular distributions into energy distributions for elastic nuclear reactions, one can integrate the differential angular cross sections over all angles. This method is similar to techniques used in photoionization, where energy distributions are derived from angular distributions. The discussion highlights that while the photoelectric effect does not directly involve energy distribution, the integration approach remains applicable. Understanding these relationships is crucial for accurate modeling in nuclear physics. The conversation emphasizes the importance of these transformations in analyzing nuclear reactions.

Hi!

I wonder, in the case of elastic reactions with nuclear potential, how go from an angular distribution to an energy distribution?

I have relationships on differential angular cross sections for neutron and proton elastic nuclear reations and I would like to transform them into differential energy cross sections.

Do you know how to proceed ?

Thank you in advance.

At least in the field of photoionization, the energy distribution can be obtained from angular distribution by integrating the latter over all angles.
 
Exact :) the Photoelectric effect does not involve energy distribution, it is convenient =)
 

Thread 'The Effect of Linear and Rotational Motion on Measured Weight'

Consider an extremely long and perfectly calibrated scale. A car with a mass of 1000 kg is placed on it, and the scale registers this weight accurately. Now, suppose the car begins to move, reaching very high speeds. Neglecting air resistance and rolling friction, if the car attains, for example, a velocity of 500 km/h, will the scale still indicate a weight corresponding to 1000 kg, or will the measured value decrease as a result of the motion? In a second scenario, imagine a person with a...

Thread 'Coulomb gauge implies instantaneous radial electric field?'

Scalar and vector potentials in Coulomb gauge Assume Coulomb gauge so that $$\nabla \cdot \mathbf{A}=0.\tag{1}$$ The scalar potential ##\phi## is described by Poisson's equation $$\nabla^2 \phi = -\frac{\rho}{\varepsilon_0}\tag{2}$$ which has the instantaneous general solution given by $$\phi(\mathbf{r},t)=\frac{1}{4\pi\varepsilon_0}\int \frac{\rho(\mathbf{r}',t)}{|\mathbf{r}-\mathbf{r}'|}d^3r'.\tag{3}$$ In Coulomb gauge the vector potential ##\mathbf{A}## is given by...

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (First part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8 and stuck at some statements. It's little bit confused. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. Solution : The surface bound charge on the ##xy## plane is of opposite sign to ##q##, so the force will be...
