Abstract

The structure of the neutron-rich nucleus 58Ti was investigated via proton inelastic scattering in inverse kinematics at a mean energy of 42.0 MeV/nucleon. By measuring the deexcitation γ rays, three transitions with the energies of 1046(11) keV, 1376(18) keV, and 1835(27) keV were identified. The angle-integrated cross section for the 1046-keV excitation, which corresponds to the decay from the first 2+ state, was determined to be 13(7) mb. The deformation length δp,p′ was extracted from the cross section to be 0.83−0.30+0.22 fm. The energy of the first 2+ state and the δp,p′ value are comparable to the ones of 56Ti, which indicates that the collectivity of the Ti isotopes does not increase significantly with neutron number until N=36. This fact indicates that 58Ti is outside of the region of the deformation known in the neutron-rich nuclei around N=40.
