The previous publications have dealt with the angular momentum formalism of both linear and circularly polarized photons in ({gamma}, x) reactions on both polarized and unpolarized targets, and the inverse (capture) reactions initiated by polarized beams. In the present work, utilizing the general formalism of Welton, the authors deal with the linear polarization of the {gamma}-rays which are produced in capture reactions on unpolarized targets, including the possibility of having incident polarized spin {1/2} projectiles. These capture reactions are denoted by a({rvec x}, {rvec L})c, where {rvec x} is the incident polarized spin {1/2} projectile and {rvec L} represents the outgoing polarized {gamma}-ray. They present here the formalism in a convenient form, display a sample table of coefficients, and illustrate its use by means of several examples. A FORTRAN code will be made available for generating similar coefficients for other reactions.
