Projectile Coulomb excitation experiments were performed at HIE-ISOLDE at CERN with the radioactive
ion beams of 140Nd and 142Sm. Ions with an energy of 4.62 MeV/A were impinging on a 1.45 mg/cm2
thick 208Pb target. The γ-rays depopulating the Coulomb-excited states were recorded by the HPGe-array
MINIBALL and scattered particles were detected by a double-sided silicon strip detector. Experimental intensities
were used for the determination of electromagnetic transition matrix elements. A preliminary result of
the B(M1; 2+
3→2+
1 ) of 140Nd and an upper limit for the case of 142Sm are revealing the main fragments of the
proton-neutron mixed-symmetry 2+
1,ms states.
