1. Wave Packet and Heisenberg Uncertainty Relations En
... The energy of the particle is less than the potential barrier it enters, E < V0 . It is therefore certain that the particle cannot continue as a propagating wave into the barrier. The reflection probability must therefore be equal to one, R = |r|2 = 1. From their definitions, k and κ are real number ...

the Schrodinger wave equation
... Born interpretation of the wavefunction ► The 2nd derivative of a function can be taken only if it is continuous (no sharp steps) and if its 1st derivative is continuous. ► Wavefunctions must be continuous and have continuous 1st derivatives. ► Because of these restrictions, acceptable solutions to ...

Equidistant spectra of anharmonic oscillators
... We set up an example of a potential of the anharmonic oscillator type for which the timeindependent Schrodinger problem leads to a strictly equidistant spectrum for all the excited states. The general solution of this problem is strictly periodic in time (i.e., there is no spreading of arbitrary wav ...
