Neutron single-particle strength in silicon isotopes: Constraining the driving forces of shell evolution

NUCLEAR REACTIONS ⁹Be(³⁶Si, ³⁵Si), E=100 MeV/nucleon; ⁹Be(³⁸Si, ³⁷Si), E=95 MeV/nucleon; ⁹Be(⁴⁰Si, ³⁹Si), E=85 MeV/nucleon, [secondary ^36,38,40Si beams from fragmentation of ⁴⁸Ca]; measured Eγ, Iγ, γγ-coin using GRETINA array at NSCL-MSU facility; deduced momentum distributions and partial cross sections of the residual nuclei following one-neutron knockout reactions. ^35,37,39Si; deduced levels, intruder states, J, π, half-life of a level in ³⁹Si. Comparison with shell-model calculations with SDPF-U and SDPF-MU interactions.
