Popis:	The gamma-gamma angular correlations on 17 cascades in 132 Xe from the decay of 132 I have been measured using a Ge(Li)–NaI(Tl) coincidence set-up. Out of these, the correlation coefficients of the 363–772, 650–(523)–772, 877–(523)–772, 910–772 and 910–(772)–668 keV cascades have been measured for the first time. These measurements have been used to deduce the multipole mixing ratios of 11 transitions in 132 Xe. The results are: δ(363)=-0.023±0.023, δ(523)=-0.23±0.16, δ(630)=6.1 -2.5 +6.5 , δ(650)=-0.16±0.11, δ(877)=-1.2±0.5, δ(955)=-0.033±0.033, δ(1136)=0.45±0.05, δ(1173)=-0.6±0.4 or -2.0 -6.0 +0.9 , δ(1372)=0.02±0.07, δ(1399)=0.04±0.02 and δ(1442)=-0.02±0.03. The directional correlation results have also been used to deduce the spin value of 4 + to each of the 1962.9, 2394.9 and 2840.5 keV levels and those of 3 + and 3 + or 5 + to the 2669.9 and 2350.7 keV levels respectively.
