Discussion Overview
The discussion centers around deriving an explicit formula for the neutron scattering cross section as a function of energy and angle for (n,p) elastic collisions with H-1 as the target. Participants explore theoretical approaches and existing literature related to neutron scattering.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- One participant inquires about deriving a formula for the neutron scattering cross section based on energy and angle.
- Another participant suggests using center of mass coordinates and assumes isotropic scattering, noting that this applies under the assumption of elastic scattering.
- A different participant mentions attempting to use conservation of energy but only finds a relation for scattering energy as a function of angle, seeking further hints.
- One participant asserts that there is no explicit formula available, referencing the extensive literature on n-p scattering.
- Another participant provides a link to a recent paper that includes explicit formulas and references related to the topic.
- It is noted that for elastic scattering, energy is implicit in the transformation to center of mass, but other nuclear reactions may also be relevant.
Areas of Agreement / Disagreement
Participants express differing views on the existence of an explicit formula, with some asserting it does not exist while others reference literature that may contain relevant information. The discussion remains unresolved regarding the derivation of a specific formula.
Contextual Notes
Participants acknowledge the complexity of the topic, including the implications of elastic versus inelastic scattering and the need for careful consideration of energy transformations.
