66. Fingerprints of core polarization in two-nucleon transfer reactions of halo nuclei

Ricardo Broglia (INFN - Milano)

Talk

We discuss recent exclusive transfer experiments performed with low-energy beams of two-neutron halo nuclei (11Li, 12Be). We compare the measured absolute differential cross sections with theoretical results that take into account all the processes up to second order within the distorted wave Born approximation. These calculations are based on a structure model of halo...

78. Nuclear response to two-neutron transfer via the (18O,16O) reaction

Talk

A study of the structure of different nuclei was pursued at the Catania INFN-LNS laboratory by the (18O,16O) two-neutron transfer reaction at 84 MeV incident energy. The experiments were performed using several solid targets from light (9Be, 11B, 12,13C, 16O, 28Si) to heavier ones (58,64Ni, 120Sn, 208Pb). The 16O ejectiles were detected at forward angles by the MAGNEX magnetic spectrometer....

89. Multi-nucleon transfers using two-neutron halo 6He on 12C at 30 MeV using the SHARC and TIGRESS arrays at TRIUMF ISAC-II

Talk

The 12C(6He,4He)14C and 12C(6He,8Be)10Be multi-nucleon transfer reactions are studied at the TRIUMF ISAC-II facility using SHARC (Silicon Highly-segmented Array for Reactions and Coulex), a compact charged particle silicon detector array, together with TIGRESS (TRIUMF-ISAC Gamma-Ray Escape Suppressed Spectrometer), a high-efficiency germanium γ-ray detector array. The (6He,4He) transfer...

48. Study of the nuetron rich nuclei via heavy-ion double charge exchange reaction

Hiroaki Matsubara (CNS - University of Tokyo)

Talk

We are proposing a new powerful probe of heavy-ion double charge exchange (HIDCX) reaction, the (18O,18Ne) reaction, for the study of neutron rich nuclei. Ground states of 18O and 18Ne are among the same super-multiplet and the transition between them is just double spin-isospin flips keeping the spatial wavefunction unchanged. One can expect the transition is simple and its transition...
