الوصف: International audience ; The properties of a nanosecond isomer in Si 32 , disputed in previous studies, depend on the evolution of proton and neutron shell gaps near the island of inversion. We have placed the isomer at 5505.2(2) keV with J π = 5 − , decaying primarily via an E 3 transition to the 2 1 + state. The E 3 strength of 0.0841(10) W.u. is unusually small and suggests that this isomer is dominated by the ( ν d 3 / 2 ) − 1 ⊗ ( ν f 7 / 2 ) 1 configuration, which is sensitive to the N = 20 shell gap. A newly observed 4 1 + state is placed at 5881.4(13) keV; its energy is enhanced by the Z = 14 subshell closure. This indicates that the isomer is located in a yrast trap, a feature rarely seen at low mass numbers.
