Abstract.

The paper reports on the test of the newly developed RIKEN-ATOMKI CsI(Tl) array. It is demonstrated that high-quality detectors with excellent light collection efficiency and narrow resolution distribution could be produced. The setup has been commissioned in the study of the reaction of 22O + CD2. In the present paper, we summarize the results mainly on the (d, d ) channel. From the cross section for the transition between the ground state and the first 2+ state, we could deduce the “matter” deformation parameter to be βM = 0.23±0.02 by distorted wave analysis. Comparing this data with previous measurements it can be concluded that 22O isotope has moderate and similar neutron and proton deformations.
