Hi I'm trying to solve a one-dimensional quantum well problem. The problem itself is probably (or: hopefully) not too hard to solve, but I'm having a difficult time to understand how the given potential actually works. The incident particles is coming from the left, and the potential well is given by: 0 when abs(x) > a -V0 when abs(x) < a ...Where V0 > 0... I'm not sure how the particles will interact with this potential. My first thought was that it would act as a "upside down" potential barrier... What I mean is that if the particle's energy E is greater than 0, then it would act as a potential well, and if E < 0, then it would act as a barrier.. But I'm not sure at all if I'm right, or if I have misunderstood the entire thing! All help is appreciated! Thanks in advance.
