The decay properties of In-127 and In-129 have been investigated using Isotope Separation On-Line (ISOL) produced samples. In both In-127 and In-129 new beta-decaying isomeric states were observed, with half-lives of 1.04 +/- 0.10 and 0.67 +/- 0.10 s, respectively, in addition to the previously known isomers of single proton hole p(1/2) and g(9/2) character. Q(beta) measurements show that the new isomeric states are present at energies approaching 2 MeV above the ground states. The level schemes of Sn-127 and Sn-129 have been considerably extended. The modes of feeding and decay of the two mus isomers in each of the Sri nuclei are fully elucidated, including new half-life determinations. Shell model calculations on (127)Sri and (129)Sri were performed, giving results in good agreement with the new data.
