A Java Program for Solving a Simple Quantum Scattering Problem

---

Overview

---

This Java program models the H-Kr system using a Lennard–Jones (LJ) potential and solves the radial Schrödinger equation using the Numerov algorithm. It calculates the cross sections from the phase shifts and displays the results as a function of energy.

Running the Program

---

To run the program, navigate to the bin directory and execute the following command:

cd bin
java ScatterApp

Example Output

---

The program generates a plot of the total cross section as a function of energy, as shown below:

Customization

---

You can modify the program to suit your needs and perform simulations for your own projects involving the calculation of cross sections.

Dependencies

---

• OpenSourcePhysics (OSP)
• JavaPlot
