The level structure of 141Ce up to 3.7 MeV excitation energy has been investigated by the (d, t) and (3He, α) reactions using 17 MeV deuteron and 24 MeV 3He beams respectively. The angular distributions have been analyzed with standard DWBA calculations and spectroscopic factors are deduced. The experimental information is compared to unified model calculations involving both one-particle and two-particle one-hole configurations with quadrupole and octupole vibrations of the underlying N = 82 and N = 84 core.
