Detailed View at Magnetic Dipole Strengths: The Case of Semimagic 50 Ti

Le résumé fourni par la source

Magnetic dipole, M1, strengths were studied in semimagic ^{50}Ti up to the neutron-separation threshold by combining data from (d,p) one-neutron transfer, (γ,γ^{'}) real-photon scattering, (e,e^{'}) inelastic scattering at extreme backward angles, and (p,p^{'}) at E_{p}=210 MeV and extreme forward angles. The combination of all probes provided unique access to the neutron spin-flip contribution and the possibility to evaluate its role in generating the spin-flip M1 strengths. The small contribution of the neutron (1f_{7/2})^{-1}(1f_{5/2})^{+1} spin-flip transitions, which were probed with the (d,p) reaction, to the overall strength in ^{50}Ti questions the standard picture for the microscopic origin of spin-flip strength in the fp shell. For ^{50}Ti, this Letter shows that J^{π}=1^{+} states with larger neutron (1f_{7/2})^{-1}(1f_{5/2})^{+1} spectroscopic factors do not correspond to the ones with the largest B(M1;0_{1}^{+}→1_{i}^{+}) strengths.
