Barrier potential, E> V0
V(X) = 0 ( x < 0 )
= V0 ( 0 < x < a )
= 0 ( x> a )
Psi(x)1 = Aexp[ik1x] + B exp[-ik1x]
Psi(x)2 = Cexp[ik2x] + D exp[-ik2x]
Psi(x)3 = Fexp[ik1x] + G exp[-ik1x] ( K3= K1 so I put k1 )
and G = 0 because there is no reflection,
I used B.C so I get 4 functions
and I calculated and I found what is A/F .
but there is problem
exp[ik2a] and exp[-ik2a], I changed into sine and cosine
but there is remaind exp[ik1a]
I have to derive T(transmission) but there is no K1
how do I eliminate that?
this problem is from Introductory Nuclear Physics chap.2 - 1
please help me :(
