The decay of the K ϭ8 Ϫ isomer in 132 Ce with an excitation energy of 2340.2 keV has been investigated using the 120 Sn(16 O,4n) 132 Ce reaction. A half-life of 9.4Ϯ0.3 ms was determined. Two new decay paths have been found in the deexcitation of this isomer. The hindrance factors for the E1, M 2, and E3 transitions deexciting the isomer have been determined. The decay properties of the 8 Ϫ isomers in the Nϭ74 isotones are discussed. A band mixing mechanism involving the ground state and s band seems to be responsible for the behavior of the reduced hindrance factors of the E1 transitions deexciting the K ϭ8 Ϫ isomers in these isotones. A K mixing, characteristic of the axially asymmetric nuclei, may account for the reduced hindrance factors of the E3 transitions to the 5 ␥ ϩ states in 130 Ba and 132 Ce.
