Philosophiae Doctor - PhD / The Coulomb excitation of 66Ge has been performed for the rst time using \safe"
bombarding energies at the HIE-ISOLDE facility at CERN in July 2017. A particle-
coincidence experiment using the MINIBALL array and double-sided silicon detectors
has allowed the determination of transitional and diagonal matrix elements in 66Ge,
yielding new measurements of the reduced transition probability connecting the ground
state, 0+1
, and the rst excited state, 2+1
, or B(E2; 2+1
! 0+1
) value, and the spectroscopic
quadrupole moment of the 2+1
state, QS (2+1
). A relatively large B(E2) = 29:4(30) W.u.
has been extracted using beam-gated data at forward angles { less sensitive to secondorder
e ects { as compared with the adopted value of 16:9(7) W.u., but in closer agreement
with modern large-scale shell-model calculations using a variety of e ective interactions
and beyond-mean eld calculations presented in the current work. / 2022
