High School Angular distribution to energy distribution

Click For 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 'Reference frames, center of rotation, etc'

Topic about reference frames, center of rotation, postion of origin etc Comoving ref. frame is frame that is attached to moving object, does that mean, in that frame translation and rotation of object is zero, because origin and axes(x,y,z) are fixed to object? Is it same if you place origin of frame at object center of mass or at object tail? What type of comoving frame exist? What is lab frame? If we talk about center of rotation do we always need to specified from what frame we observe?
