4. At 1 MeV the Compton cross section per electron is 0.2112 barn and the Compton energy absorption cross section per electron is 0.0929 barn.

a) What is the average energy of the recoiling electron in a Compton interaction at this energy?

b) Computer the Compton mass attenuation and mass absorption coefficients at 1 MeV for i) aluminum ii) water

Expert Solution

Given: E = h=1 MeV, = 0.2112 b, = 0.0929 b

a) Average energy of the recoiling electron is

b) Compton Mass attenuation coefficient

(i) For Aluminium, A = 26.982 g/mole, Na is Avogadro's number, Z = 13, = 0.2112 b

(ii) For water

Z = 7.51, A = 18 g/mol, = 0.2112 b

Consider an electron beam of uniform circular cross-section with a diameter of 1 mm. The electrons are accelerated from the cathode to the anode, which are separated by 1 m. The electrons are generated at the cathode and therefore have negligible velocity at this position. The electrons accelerate at a rate of 108 ?/?2 between the cathode and anode. The current density at the anode is 104 ?/?2 . Find the current density as a function of position between the...

Compton ScatteringExercise 10:The equation for Compton scattering of a photon off of an electron is.?′=?+(ℎ??)(1―cos?)If using nm for wavelength, the quantity (h/mc) is 0.00242631nm (to a ridiculous number of sig figs, but you can round off later.) Notice how λ’ is always bigger than λ, because the scattered photon always has less energy – unless the angle is zero, which means nothing happened.A) Suppose a photon of energy 248eV scatters off of an electron in such a way as to...

In a laboratory an electron is given a kinetic energy of .400 MeV and sent to the right. A spacecraft moves to the right with a speed of .50c with respect to the laboratory. What would be the kinetic energy of the electron as measured by someone in the spacecraft's frame of reference? The mass of an electron is 9.11x10-31 kg and the mass energy of an electron is .511 MeV.

(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.)
