SUMMARY

This discussion centers on the need for nuclear scattering applets that can handle potentials of arbitrary shapes, as well as the use of partial wave expansion techniques. Participants express interest in simulation tools that provide physical intuition for complex nuclear reactions, particularly through the use of applets. A specific simulation link, http://www.numathics.com/arens/scattering/ssObst.html, is shared, which utilizes the Distorted Wave Born Approximation (DWBA) for calculations. The conversation highlights the challenges of creating lightweight applets for many-body nuclear interactions compared to simpler optical simulations.

PREREQUISITES
  • Understanding of nuclear reactions and scattering theory
  • Familiarity with Distorted Wave Born Approximation (DWBA)
  • Knowledge of partial wave expansion techniques
  • Basic concepts of simulation applets in physics
NEXT STEPS
  • Research advanced nuclear scattering applets for arbitrary potential shapes
  • Explore the implementation of Distorted Wave Born Approximation (DWBA) in simulations
  • Learn about partial wave expansion methods in quantum mechanics
  • Investigate the development of lightweight simulation applets for many-body interactions
USEFUL FOR

Researchers, physicists, and educators interested in nuclear physics, particularly those looking to enhance their understanding of scattering processes and simulation techniques.

Hello

I have trouble understandig nuclear reactions. Does anyone know some good scattering applets on a potential(of arbitrary shape;not 1D).

I am interested also in discussing partial wave expansion. And if there exists an applet to show me how can I approximate a plane wave with spherical ones.

Hy,

why do you concentrate on simulation applets ? You have a specific calculation goal ? MC simulations are usually quite heavy, thus it is uncommon to refer to them as "applet" :wink:
 
With an applet I can feel much better the physics.
I found for example this simulation
http://www.numathics.com/arens/scattering/ssObst.html

The actual calculation is done with DWBA, but in order to understand how DWBA works I must have a physical intuition prepared.
 
Oh yes, I agree that applets are very convenient to get a physical sens of what is going on. In the case of optics/electromagntism (which I am not an expert) the equations are failry simple and fast applets can be written down. But in the case of many-body nuclear interactions, I do not expect that you will find such an applet. I might be wrong, and I am aware of being of very little help :biggrin:
