The high-spin states of 140Pm have been investigated through the reaction 126Te(19F, 5n) at a beam energy of 90 MeV. A previous level scheme based on the 8− isomer has been updated with spin up to 23 ℏ. A total of 22 new levels and 41 new transitions were identified. Six collective bands were observed. Five of them were expanded or re-constructed, and one of them was newly identified. The systematic signature splitting and inversion of the yrast πh11/2⊗νh11/2 band in Pr and Pm odd–odd isotopes has been discussed. Based on the systematic comparison, two ΔI = 2 bands were proposed as double-decoupled bands; other two bands with strong ΔI = 1 M1 transitions inside the bands were suggested as oblate bands with γ ∼ −60°; another band with large signature splitting has been proposed with oblate-triaxial deformation with γ ∼ −90°. The characteristics for these bands have been discussed.

Radionuclide production was studied by bombarding Cu, W and Pb targets with a 250 MeV proton beam. The data were obtained by using the off-line γ-spectroscopy method. Six nuclides in Cu, 28 nuclides in W and 34 nuclides in Pb targets were identified and their cross sections were determined. The measured results were compared to other experiments with isotopic Cu and W targets. Corresponding simulations using the MCNPX transport code were also performed to compare the measurements. In the simulations, eight different models or combinations of intranuclear cascade and de-excitation models were introduced. The comparison indicated that most cross sections were fairly reliably predicted for nuclides in the spallation mass region, but differ greatly for nuclides in the medium and fission mass regions.
