Abstract
The previously accepted spin values of the 991 and 1599 keV levels in 140Sm have been revised and established as 2+ and 0(+), respectively. The γ-γ angular correlation method was used to determine the new spin values. The excited low-spin levels in 140Sm were populated in the 140Eu→ 140Sm and 140Gd 140Eu→ 140Sm decays. The 140Gd and 140Eu nuclei were produced in the 112Cd + 32S reaction at a beam energy of 155 MeV. [ABSTRACT FROM AUTHOR]
