Abstract: MM.00007 : Coulomb excitation of 52Ca
3:30 PM–3:45 PM
The Coulomb excitation of 52Ca at 240 MeV/nucleon has been measured. In neutron-rich nuclei, it is known that the magic numbers evolve with a neutron-proton ratio (i.e. disappearance at N =8,20). For Calcium isotopes, 52Ca is supposed to be the doubly magic nucleus with Z=20 and N =32, possible new magic number, based on the relatively high 2+1 energy. And the reduced transition probability B(E2;0+1→2+1 ) has not yet been measured. To disclose the nuclear collectivity, we have measured the B(E2) value of 52Ca with Coulomb excitation.
The experiment was performed by using SAMURAI spectrometer at RIKEN RIBF. The beam at 240 MeV/nucleon impinged on a lead and carbon target, and the reaction residue was identified by using the SAMURAI spectrometer. The de-excitation γ-ray from 52Ca was detected by using the CsI(Na) array CATANA and LaBr3 detectors.
In the present talk, the Coulomb excitation cross section to the first 2+ state of 52Ca will be reported.
