| Abstract: | 176,177Ir were produced by irradiation of141Pr with40Ar. β-delayed γ-rays of176,177Ir were observed for the first time. From γγ-coincidence data decay schemes could be constructed. A new half-life of177Ir was obtained yielding t1/2=30 (2) s. α-branching ratios of 3.1(6) % for176Ir and 0.06(1)% for177Ir were measured. |
