the attachment here shows a potential well and i am practicing writing down wave functions in each region and boundary conditions (for this problem I suppose the boundaries would be x= -a, 0, b.
i think that for this problem i need 4 functions and i thought that they may be:
when
x<-a (1) = 0
-a<x<0 (2) = Asin(k1x) + Bcos(k1x)
0<x<b (3) = Csin(k2x) + Dcos(k2x)
b>x (4) = 0
where
k1 = ([tex]\sqrt{}2mE[/tex])/[tex]\hbar[/tex]
k2 = ([tex]\sqrt{}2m(E-Vo))/\hbar[/tex]
and i think at the boundary x = -a and b the wave function is continuous and at x=0 the wave function and the first derivative is continuous.
Is this right?
thanks
