Answer to Problem 36P
The maximum fractional energy loss for the
Explanation of Solution
Write the Compton shift equation.
Here,
The energy of the gamma ray and its wavelength are inversely proportional. The maximum energy loss will occur for maximum increase in wavelength of the gamma ray.
The value of
Substitute
Write the equation for the fractional energy loss of the Gamma ray.
Here,
Write the equation for the energy of incident gamma ray.
Here,
Write the equation for the energy of the scattered gamma ray.
Here,
Put equations (IV) and (V) in equation (III).
Write the equation for the Compton shift in the gamma ray’s wavelength.
Rewrite equation (VII) for
Put equation (VII) in the numerator of equation (VI) and replace denominator of equation (VI) by (VIII).
Rewrite equation (IV) for
Put equations (II) and (X) in equation (IX).
Conclusion:
The value of

Answer to Problem 36P
The maximum fractional energy loss for the
Explanation of Solution
Equation (XI) can be used to find the fractional loss of the gamma ray when it is Compton scattered from the free proton by using the mass of the proton in the equation.
Conclusion:
The mass of proton is
Substitute
Therefore, the maximum fractional energy loss for the

- 13.87 ... Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion? What about for a flight from Mars to the earth? (b) How long does a one- way trip from the the earth to Mars take, between the firings of the rockets?
