1. The problem statement, all variables and given/known data A particle of mass m and E<V0 approaches from the left and encounters a potential barrier, assume the amplitude of the incoming particle is A. Write the time independent wavefunction for x>0 and x>0 at t=0 E is definite. Find the reflection coefficient of the particle. 2. Relevant equations R=(abs(Ar)2/abs(Ai)2) 3. The attempt at a solution for x<0 where the potential is 0, [tex]\Psi(x)[/tex]=Aexp(-[tex]\alpha[/tex]x) and where x>0 where the potential is >E, [tex]\Psi(x)[/tex]=Acos(k0x) is it correct? does both of the amplitudes are the same?
