The lifetimes of the 21+ and 41+ states Po208 were measured in α-transfer reaction Pb204(C12,Be8)Po208 by γ-ray spectroscopy utilizing recoil distance Doppler shift method. newly extracted transition strengths alongside ones decay 22+ state compared to results large-scale shell-model calculations using an effective interaction derived from realistic CD-Bonn nucleon-nucleon potential. comparison indicates importance quadrupole isovector excitations valence shell for a fine tuning two-body matrix elements interaction.Received 17 May 2021Accepted 15 July 2021DOI:https://doi.org/10.1103/PhysRevC.104.024311©2021 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasCollective levelsLifetimes & widthsNuclear structure decaysShell modelProperties190 ≤ A 219Nuclear Physics
