Weblink 18.3 The energy levels and wavefunctions of the Morse oscillator

This application shows how the energy levels and wavefunctions vary as the Morse parameters are changed (see section 18.7.3). The potential energy is shown by the green curve, and the energies of the levels are represented by the horizontal lines. For each level, the corresponding wavefunction is plotted assuming that the horizontal line (representing the energy) is the x-axis. The wavefunctions are shown in blue in the classical region and in red in the non-classical region. The quantum number v of each level is shown on the right, and on the left are the values of ω_e and ω_ex_e resulting from the Morse parameters set by the sliders.

• Move the sliders to vary the force constant, the mass of the particle and the wavefunction amplitudes
• Use the radio buttons to select whether or not the wavefunction is displayed, or to select display of the square of the wavefunction
• For best performance, Google Chrome is recommended
