Dear all,

I am trying to simulate the penetration of the wavefunction into a potential barrier consisting of two barrier steps of different heights, V1 and V2.

My code looks like that:

> restart;
> m := 0.91e-30;h := 0.1055e-33; V1 := 10*0.16e-18; V2 := .8*V1;a := 0.10e-9;En := .6*V1; w := En/h;
                      ...
