Study of proton and deuteron pickup reactions (d,3He), (d,4He) with 8He and 10Be radioactive beams at ACCULINNA-2 fragment separator

The extremely neutron-rich systems 7H, 6H were studied in the 2H(8He, 3He)7H and 2H(8He, 4He)6H proton and deuteron pickup reactions with a 26 AMeV secondary 8He beam produced at the new ACCULINNA-2 fragment separator. In addition, the same proton and deuteron pickup reactions were generated using the 42 AMeV 10Be beam, and the population of low-lying 9Li and 8Li states was measured in reactions 2H(10Be,3He)9Li and 2H (10Be,4He)8Li, respectively. The latter were used as reference measurements in order to check the setup cali-bration over the excitation energy of 7,6H and to determine the real experimental energy resolution which was compared with Monte Carlo calculations. The corresponding results obtained for the superheavy hydrogen systems 7H, 6H are presented and discussed. Typical excitation spectra of the 9Li and 8Li nuclei are also shown.

Automated summary

The extremely neutron-rich systems 7H and 6H were studied using 26 AMeV and 42 AMeV 8He and 10Be beams produced at ACCULINNA-2 fragment separator. Proton and deuteron pickup reactions 2H(8He, 3He)7H and 2H(8He, 4He)6H were used to investigate these systems, and the population of low-lying 9Li and 8Li states was also measured using reactions 2H(10Be,3He)9Li and 2H(10Be,4He)8Li. The experimental energy resolution and excitation spectra of 7H, 6H, 9Li, and 8Li were discussed and compared with simulations.
