Structure of the 1d2s Shell from the Data on Single-Nucleon-Transfer Reactions

Measurements of the gamma-quanta angular distributions emitted from neutron inelastic scattering on 28Si

“…New experimental possibilities for studying unstable nuclei with neutron excess made it possible to trace the changes in the shell structure with the neutron asymmetry growth up to the extremely neutron-rich double-magic 42 Si nucleus [1,2], and to obtain the first experimental evidence of the formation of proton density bubble in the 34 Si [3]. New experimental results are a challenge to theoretical considerations and make it necessary to consider the chain of Si isotopes in general, including model calculations and experimental data for stable isotopes 28,29,30 Si [4].…”
