Abstract
The use of the Compton polarimeter is discussed for the measurement of linear polarizations of gamma rays from aligned nuclear excited states. A set of formulas is given for calculating the polarization-correlation of any member of a multiple gamma-ray cascade and for calculating the Compton scattering asymmetry expected from a polarization measurement. Corrections for the finite geometry of the polarimeter are discussed and simple approximate formulas are given for calculating the geometrical correction coefficients. The results of exact numerical computer calculations for one sample geometry are compared with the results of the approximate formulas. The mechanical construction and electronic circuitry for a typical Compton polarimeter and the shape of the pulse height spectrum obtained by summing the pulses from the scattering and absorbing detectors are discussed.
