Problem 5: Find the diﬀerential and total cross sections in the ﬁrst Born approximation for elastic scattering of a particle of mass m, which is initially traveling along the z-axis, from a nonspherical, double-delta potential V (~ r) = V0δ(~ r − aˆ k)+V0δ(~ r+aˆ k), where ˆ k is the unit vector along the z-axis.

(from Reif, Chapter 12, problem 5) The total scattering cross section for an electron-air molecule collision is about 10^(-15)cm^2 At what gas pressure will 90 percent of the electrons emitted from a cathode reach an anode 20 cm away? (Assume that any electron scattered out of the beam does not reach the anode; i.e. neglect multiple scattering.)
