CNO cycle: "soft E1" mode of the Ne-17 excitation in the Ne-17+gamma -> O-15+2p reaction
Paper i proceeding, 2016

The O-15(2p, gamma) Ne-17 reaction is studied using the time-reversed reaction of the Ne-17 E1 Coulomb dissociation on lead target in the context of nuclear astrophysics. Looking for the relation between the data on the Coulomb excitation and the astrophysical 2p-capture rate, one faces problem to extract the Coulomb E1 strength function from the measured Coulex cross section. We use a number of phenomenological approaches to estimate influence of such processes as Coulomb-nuclear interference, populations of states with different J(pi), etc. We calculate the Ne-17+ 2p astrophysical capture rate and compare the results with different calculations.
