A wavefunction with this shape is the propagator of the diffusion equation. The normalizable solution to the Schrödinger equation for a free particle is typically assumed to be a wavefunction with this shape. Because the Fourier transform (15[1])of a wavefunction with this shape also has this shape, (15[1])those wavefunctions (15[1])satisfy the lower bound of the uncertainty principle. A wavefunction with this shape is the ground state of the quantum harmonic (*) oscillator. Uniquely, "spreading" wavepackets with this shape maintain this shape as they propagate, with their width "sigma-x" growing linearly in time. The idealized output of a laser is a beam whose intensity profile is this distribution, which is proportional to "e to the negative x-squared." For 10 (10[1])points, name this waveform that is normally distributed about a mean. ■END■ (10[1])
