Abstract

Magnetic dipole, M1, strengths were studied in semi-magic 50Ti 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 Ep = 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 (1f7/2)−1(1f5/2)+1 spin-flip transitions, which were probed with the (d,p) reaction, to the overall strength in 50Ti questions the standard picture for the microscopic origin of spin-flip strength in the fp shell. For 50Ti, this letter shows that Jπ = 1+ states with larger neutron (1f7/2)−1(1f5/2)+1 spectroscopic factors do not correspond to the ones with the largest B(M1;0+1 → 1+i) strengths.

AB  - Magnetic dipole, M1, strengths were studied in semi-magic ^50Ti 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 ^50Ti questions the standard picture for the microscopic origin of spin-flip strength in the fp shell. For ^50Ti, 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.
