(see attachment for figure and question)
a) From figure 1 express Epot(x) as a function of x.
b) For the range of x covered by figure 1 sketch the wave function of the bound state of lowest energy; explain briefly the form taken by in the direction of region x.
The solution provides an expression for potential energy, A sketch and explanation of the wave function (for the bound state of lowest energy) is also provided. Finally, a classical account and step by step calculations for collision of the particles is given.
