Abstract
By the Coulomb dissociation of 17Ne, the time-reversed reaction 15O(2p, γ)17Ne has been investigated. This reaction might play an important role in the rp process, as a bypass of the 15O waiting point. The secondary 17Ne ion beam of 500 AMeV has been dissociated on a Pb target, and the reaction products have been recorded with the LAND-R3B experimental setup (GSI). This experiment allows to determine the Coulomb dissociation cross section σCoul, which can be converted into a photo-absorption cross section σphoto, and a radiative-capture cross section σcap for the 15O(2p,γ) 17Ne reaction. Additionally, informations about the structure of the 17Ne nucleus, a possible two-proton halo, may be obtained. The analysis is still in progress.
