Enhanced quadrupole collectivity at N = 40: the case of neutron-rich Fe isotopes.
The transition rates for the 2(1)+ states in (62,64,66)Fe were studied using the recoil distance Doppler-shift technique applied to projectile Coulomb excitation reactions. The deduced E2 strengths illustrate the enhanced collectivity of the neutron-rich Fe isotopes up to N = 40. The results are interpreted using the generalized concept of valence proton symmetry which describes the evolution o...
متن کاملNontrivial aspects of the onset of nuclear collectivity: Static moments.
We consider several topics concerning static magnetic dipole and electric quadrupole moments (μ and Q) as signatures of the onset of nuclear collectivity. Having previously noted that in Cr there is an abrupt change of sign in Q of yrast states with J = 10, 12, and 14 relative to lower J states, we discuss whether these states are oblate or prolate. We next show that configuration mixing leads ...

متن کاملQuadrupole collectivity in silicon isotopes approaching neutron number N = 28
Quadrupole deformation parameters, |β2,(p,p′)|, have been deduced for 36,38,40Si from measured inelastic proton-scattering cross sections. Due to the strong Z = 14 subshell gap, low-lying quadrupole collectivity in these nuclei is attributed to the excitation of valence neutrons. Enhanced collectivity at N = 26 indicates a reduced N = 28 shell gap at large neutron excess in this chain of isotop...
