1. The problem statement, all variables and given/known data A potential well with V(x)=0 for x<0 and V(x) = Vo for x>0. The particle has energy E greater than Vo and is incident from the left side. Calculate the reflection coefficient. 2. Relevant equations Relfection coefficient is given by R= (B*B)/(A*A) 3. The attempt at a solution I think that the time independent Schrodinger equation for the two regions are x<0 (-hbar/2m)dphisquared/dphi =Ephi(x) and x>0 ((-hbar/2m)dphisquared/dphi +Vo phi = Ephi(x) the solutions to this x<0 Aexp(ik1x) +Bexp(-ik1x) = phi(x) x>0 Cexp(ik2x) is this right carrying this through and equating two solutions at x=0 A+b = C and equating differentials at x=0 gives ik1(A-B) = -ik2C/k1 but when I solve for A and B i get A=(c/2)(1-ik2/k1) B=(c/2)(1+ik2/k1) when I find R i get R=1 which must wrong because particle is not always reflected it should pass over the potential barrier?
