From angular correlation measurements with the 29Si(α, nγ) 32S reaction the 6 762-keV level has been assigned Jπ = 5-. Four new levels of 32S have been observed at Ex = 7 567-, 8 345-, 9 464- and 9 637-keV. The 7 567-keV level has been assigned Jπ = 5+ and the 8 345-keV level is a good candidate for the lowest 6+ state. The two higher levels are probably negative parity high spin states.
