WebOur modified equation (some people call it the imaginary-time Schrödinger equation) has some nice properties. The first thing to notice is that if we happen to guess the ground state wave function, then H Φ 0 ( x ) = E 0 Φ 0 ( x ) {\displaystyle H\Phi _{0}(x)=E_{0}\Phi _{0}(x)} and the time derivative is zero. WebI'm not a physicist, but Numerov's method is used to finding stationary solutions (time-independent Schrodinger equation). When you say scattering and give a potential with that shape it makes me think you want to see how a wave packet is dynamically affected (time-dependent Schrodinger equation). The documentation for NDSolve gives some examples.
