## Homework Statement:

- Show that for a potential of type ๐ (๐โ) = ๐๐ฟ (๐โ), where ๐ is a constant and ๐ฟ (๐โ) is the delta function of Dirac 3D. Using the Born approximation, determine the scattering amplitude and derive an expression for ๐ so that the scattering length is b.

## Homework Equations:

- f(ฮธ) = C โซ dr rV(r)sin(qr)

I tried to calculate the fourier transform to get the amplitude, but I got lost
