The potential barrier is defined by V(x) =((A^2-(x^2)*(b^2))^0.5Â Â where x is less than or equal toA/b.
First we want to sketch V(x)
Then we run a particle into it wth mass m and energy E (which isless than A). Now that we have run the particle into it we areasked to derive an expression for the probability of penetration interms of D = E/A and sin (y) = bx/A.
Finally, we are to evaluate our expression in numerically forD=0.1 to 1.0 in steps of 0.1 for an electron stricking such abarrier with A=10 eV and b=2eV/angstrom.
Help!! I have no idea how to start this monster. How do I sketchthis??
