Measurement of the Two-Halo Neutron Transfer Reaction <sup>11</sup>Li(p,t)<sup>9</sup>Li at 62.4 MeV
ORAL
Abstract
We report the measurement of differential cross section of the 11Li(p,t)9Li reaction performed at TRIUMF. Previous investigation of the reaction was reported at lower energy of 3A MeV [1]. Present data were taken at higher energy where the direct reaction mechanism is expected to be more dominant. It will be shown that the present measurement shows the transition to a higher excited state than the previous report.
We used the ISAC-II facility to accelerate 11Li to 62.4 MeV and the IRIS facility was used for measuring the 11Li(p,t) reaction. This experimental data were simultaneously taken with the published experiment of (p,p')[2].
The transition to the second excited state of 9Li was observed for the first time. . The presentation will describe the experiment and analysis.
