Abstract: Detailed α-decay studies of 179TIg and its daughter products 175Aug and 17lIrg were carried out in two complementary experiments at the mass separator ISOLDE (CERN) and velocity filter SHIP (GSI). First unambiguous determination of the α-decay properties of 175Aug was performed as follows: Ea = 6433(4) keV, T1/2 = 207(7) ms, and α-decay branching ratio 90(7)%. First determination of the α-decay branching ratios for 179TIg and 171Irg was also made:ba(179TIg) = 60(2)% and ba(171Irg) = 15(2)%. The spins of the ground states in 175Au and 171Ir are established as l/2+. [ABSTRACT FROM AUTHOR]
