Fourier mn
Homework Statement
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.
Homework Equations
R=(abs(Ar)2/abs(Ai)2)
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?
