Description
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.
