Abstract
The levels in 146Sm have been investigated through the electron capture of 146Eu, and by means of the (α,2n), (d,t), and (3He,α) particle reactions. Spins and parities of a large number of levels have been determined by combining the results of γγ(θ) and γ(θ) distributions in the electron capture and (α,2n) reactions respectively and electron spectra associated with the (α,2n) reaction. The low lying states of 146Sm can be interpreted in terms of the vibrational model. The high spin states populated at higher excitation seem to be associated with particle excitations.
