Description
The properties of collective 1π=1+ states in double even semi-magic nucleus 140 Ce are investigated in spherical random phase approximation (RPA). The calculation of the B(M1) strength, elastic γ-scattering cross section σγ(ω) and γ-decay width Γγ(ωi) show that in 140 Ce the isovector spin-spin interactions concentrate the main strength of M 1 transition at energy 7.89 MeV where the isovector spin-flip magnetic resonance may appear. These predictions are consistent with the observed M 1 strength in 140 Ce which is seen to be concentrated within a range of about 0.8 MeV centered at an excitation of 7.95 MeV. (authors)
