In the Born approximation (the first term of the Born series), the scattering amplitudes are given by the Fourier transform of the scattering potential: f(θ, φ) = - 1/(4π) ∫ d^3~r e^(-i(~ks-~ki)·~r)U(~r). (7) Here, ~ki is the momentum of the incident particle, and ~ks is the momentum of the scattered particle, which has the same magnitude but possibly a different direction. The angle between them is θ. Consider a scattering potential that is translationally invariant. That is,

10.8 There is considerable interest in delivering drugs to the brain for the treatment of cancer or degenerative nerve diseases. Delivering drugs to the brain via the cir- culation is extremely difficult because the microvascu- lar endothelia are impermeable to most molecules. Implanting a polymeric capsule containing the drug of interest represents one possible approach to delivering drugs locally. Consider a long cylindrical implant of radius $R$ and length $L$. The implant dissolves at a constant rate $R_0$. The drug is released at the surface as a result of polymer dissolution. As the drug diffuses through the brain tissue, it is metabolized by a first-order reaction with a rate coefficient $k_c$. Assuming steady-state diffu- sion and assuming that the drug is diffusing into a region of length $\Lambda$, determine whether a reaction of the following drugs is diffusion limited: $R = 0.1$ cm $L = 1$ cm $\Lambda = 1$ cm Anticancer drug $k_c = 2.8 \times 10^{-4} s^{-1}$ $D_{eff} = 5 \times 10^{-6} cm^2 s^{-1}$ Nerve growth factor $k_c = 1.1 \times 10^{-3} s^{-1}$ $D_{eff} = 1 \times 10^{-6} cm^2 s^{-1}$
