Sunflower - In-beam gamma-ray spectroscopy at the RIBF

The structure and nature of the pygmy dipole resonance (PDR) state below and above the neutron threshold in exotic nuclei is still far away from beeing understood. Recent experimental observations give only few information on this subject. New and combined experiments using different methods are needed. The presentation we will give information on how relativistic coulomb excitation combined...

This letter of intent is aiming to investigate the collective nature of low lying Octupole states, in the region of the N=Z 112Ba, by measuring the octupole deformation and the neutron and proton contribution to the octupole excitation by means of the isovector (p,p’) and isoscalar (d,d’) reactions, in inverse-kinematics, of secondary BigRIPS beams in the target position of the DALI2 -...

The present proposal aims to exploit the unique capabilities of BigRIPS in delivering Pb beams from 238U fragments at RIKEN. Coulomb excitation studies of fast radioactive beams will be extended to very neutron-deficient Pb nuclei and to excited states inaccessible with other methods. The measurements of B(E2) values to the 2+ states in the even-mass 184-188Pb nuclei in Coulomb excitation...
