3-D Hydrogen Atom Probability Densitites 

written by Jose Ignacio Fernández Palop

The 3-D Hydrogen Atom Probability Densitites model simulates the probability density of the first few (n = 1, 2, and 3, and associated l and m values) energy eigenstates for the Hydrogen atom (the Coulomb potential). The main window shows the energy level diagram for the solutions to the Coulomb potential in three dimensions. States may be selected either by using the dropdown menu item or by using the energy level diagram and clicking a dark green level, with specific n, l, and m values) which will turn bright green and change the state shown in the 3d visualization window. The probability is shown with a 3d cloud, with higher probability shown as a darker sphere.

The simulation uses either simple 3D or Java 3D (if installed) to render the view the probability densities. If Java 3D is not installed, the simulation defaults to simple 3D using Java.

The 3-D Hydrogen Atom Probability Densitites model was created using the Easy Java Simulations (EJS) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_qm_hydrogen3d.jar file will run the program if Java is installed.
