N2 - We report on the first in-beam γ-ray spectroscopy study of the very neutron-rich nucleus S46. The N=30 isotones S46 and Ar48 were produced in a novel way in two steps that both necessarily involve nucleon exchange and neutron pickup reactions Be9(Ca48,K48)X followed by Be9(K48,Ar48+γ)X at 85.7MeV/u midtarget energy and Be9(Ca48,Cl46)X followed by Be9(Cl46,S46+γ) X at 87.0MeV/u midtarget energy, respectively. The results are compared to large-scale shell-model calculations in the sd-pf shell using the SDPF-NR effective interaction and Z-dependent modifications.
