The feasibility of measuring angular distributions of γ rays emitted from intermediate-energy exotic nuclei to determine multipolarities of γ -ray transitions is shown. Plots of γ -ray angular distributions for various excitation mechanisms are presented. The influences of the percentage of alignment in an excited state, the beam velocity, the spins of the initial and final states, the minimum impact parameter, the atomic number and mass of the projectile and target, and the excitation energy are discussed. The aim is to illustrate that γ -ray angular distribution experiments can be succesfully performed with intermediate-energy beams.
