Quadrupole collectivity in neutron-rich Fe and Cr isotopes.
Intermediate-energy Coulomb excitation measurements are performed on the N ≥ 40 neutron-rich nuclei (66,68)Fe and (64)Cr. The reduced transition matrix elements providing a direct measure of the quadrupole collectivity B(E2;2(1)(+) → 0(1)(+)) are determined for the first time in (68)Fe(42) and (64)Cr(40) and confirm a previous recoil distance method lifetime measurement in (66)Fe(40). The resul...

متن کاملEnhanced 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 کاملExotic Structure of Carbon Isotopes
We studied firstly the ground state properties of C-isotopes using a deformed Hartree-Fock (HF)+ BCS model with Skyrme interactions. Shallow deformation minima are found in several neutron−rich C-isotopes. It is shown also that the deformation minima appear in both the oblate and the prolate sides in 17C and 19C having almost the same binding energies. Secondly, we carried out shell model calcu...
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...
