We study the decays t-tilde{sub 2}{yields}t-tilde{sub 1}HH, t-tilde{sub 2}{yields}t-tilde{sub 1}ZZ, t-tilde{sub 2}{yields}t-tilde{sub 1}W{sup +}W{sup -}, and t-tilde{sub 2}{yields}t-tilde{sub 1}ZH, with an eye towards measuring the CP-violating supersymmetric parameters contained in these processes. We find that t-tilde{sub 2}{yields}t-tilde{sub 1}HH tends to have the largest CP asymmetry and width, and is perhaps the most favorable experimentally. These decays are sensitive primarily to {phi}{sub A{sub t}}, the phase of the trilinear coupling A{sub t}.
