In the Born approximation, the first-order scattering amplitude is given by the Fourier transform of this quantity.
In the Born approximation, the first-order scattering amplitude is given by the Fourier transform of this quantity. The transmission coefficient for a one-dimensional tunneling process in which this quantity differs stepwise between two regions is zero when this quantity is equal to h-bar squared times the wave vector squared over twice the mass. A quantum system in which this quantity is proportional to a Dirac delta function admits only a single bound state having energy proportional to the square of the delta function coefficient. This quantity enters into the Schrodinger equation for a single particle as it is added to the square of the momentum over twice the mass to form the Hamiltonian. For 10 points, identify this quantity in quantum mechanics that represents an externally imposed energy, such as that which might come from a field, and examples of which include the harmonic well.
