Abstract

The present article reports second background considerations for the experimentally obtained H-2(Be-7,H-3)Be-6 differential cross sections. The one-neutron transfer reaction was measured in inverse kinematics by using radioactive Be-7 (t (1/2) = 53.2 days) beams at the Holifield Radioactive Ion Beam Facility of the Oak Ridge National Laboratory in 2004 in order to search for the resonances in the unbound Be-6 nucleus. Resonances in this nucleus would affect the He-3(He-3,(2) p)He-4 reaction rate of the proton-proton chain occurring in stars such as our sun. The result shows, however, that the direct transfer to Be-6 resonances is not particularly strong compared to other reaction channels that can produce tritons in the exit channels. The goals of the present work is to better understand the cross section data from transfer reaction measurements by adopting background considerations using the three-body continuum. (AU)
