Abstract: The decay out of the πh 11/2νh 11/2 band to the known low-energy levels in 132La was studied using the reaction 100Mo + 36S at 160 MeV beam energy. The low-energy level scheme has been further developed and unambiguous spin and parity values have been assigned to the levels connecting the band to the 6- isomeric state. According to the new level scheme the spins in the πh 11/2νh 11/2 band are shifted up by one unit compared to the earlier tentative experimental values. The obtained new spins prove the existence of signature inversion in 132La and give further support to the spin assignments made for the πh 11/2νh 11/2 bands in the neighbouring odd-odd La isotopes from level energy systematics.
