• The dlcay of ^<135>Ce was studied with a π√<2> iron-free β-spectrometer, a Ge(Li) detector and an e^--γ delayed coincidence technique. From internal conversion and γ-ray studies 21 new transitions were observed. The multipolarities with mixing ratios of 10 transitions were determined from the L-subshell conversion ratios. From these results a revised decay scheme is proposed as follows: 0[5/2^+], 119.47[7/2^+], 206.37[5/2^+], 265.42[3/2^+], 299.92[1/2^+], 665.30[5/2^+], 783.38[3/2^+], 828.20[3/2^+], 872.15[1/2^+(3/2^+)], 984.29[1/2^+,3/2^+], 117.16[3/2^+(1/2^+)], 1438.95[1/2^+,3/2^+] and 1767.3[1/2,3/2], where level energy are written in keV. Large E2 enhancements are found for the 34.5, the 86.9, the 265.4 and the 299.9 keV transitions.
