141. And so it all began: Personal memories of the man behind the scientist

Prof. Marialuisa Aliotta (University of Edinburgh)

22/06/2017, 11:00

Invited talk

At the time I began my scientific career as a PhD student under Prof Claudio Spitaleri’s supervision, the Trojan Horse Method was still in its infancy. Like with any new-born idea, it took time and effort and passion to plant the early seeds that would eventually develop into a now well-established method in nuclear astrophysics research. In this talk I will offer my own recollection of...

36. Theory of the Trojan-Horse Method - From the original idea to actual applications

Dr Stefan Typel (IKP, Technische Universität Darmstadt)

22/06/2017, 11:15

Special session on Claudio Spitaleri achievements

Invited talk

Breakup reactions were proposed in 1986 by Gerhard Baur as an indirect method to investigate low-energy charged-particle reactions relevant for nuclear astrophysics [1]. This so-called 'Trojan-Horse method' (THM) allows to extract cross sections of two-particle reactions from suitable transfer reactions with three particles in the final state using quasifree scattering conditions. A...

121. Clustering of light nuclei and electron screening in astrophysical environments (EPS Invited Speaker)

Prof. Carlos Bertulani (Texas A&M University-Commerce)

22/06/2017, 11:30

Special session on Claudio Spitaleri achievements

EPS Invited Speaker

Accurate measurements of nuclear reactions of astrophysical interest within, or close to, the Gamow peak show evidence of an unexpected effect attributed to the presence of atomic electrons in the target. The experiments need to include an effective “screening” potential to explain the enhancement of the cross sections at the lowest measurable energies. Despite various theoretical studies...

134. Coulomb dissociation - another Trojan Horse

Dr Tohru Motobayashi (RIKEN Nishina Center)

22/06/2017, 11:45

Invited talk

I start with my experience for the quasi-free process, which is on the 1H(d,2He)n reaction, where 2He denotes a system of two protons in their unbound singlet S state. The data taken at Saturne in late 1980s were analyzed with plane-wave impulse approximation. The tensor analyzing powers and even the absolute magnitudes of the differential cross sections have been successfully explained. That...

135. Subtilities in Stars: Indirect Evidence of Mixing Married to Indirect Nuclear Physics Methods

136. "Other" indirect methods for Nuclear Astrophysics

Dr Livius Trache (IFIN-HH Bucharest)

22/06/2017, 12:15

Invited talk

In the house of Trojan Horse Method (THM), I will say a few words about "other" indirect methods we use in Nuclear Physics for Astrophysics. In particular those using Rare Ion Beams that can be used to evaluate radiative proton capture reactions. I addition a few words about work done with the Professore we celebrate today. With a proposal, and some results with TECSA, for a simple method to...

138. Alpha-cluster structure populated in the resonance reactions induced by rare beams

Dr Vladilen Goldberg (Cyclotron Institute, Texas A&M University, College Station, Texas, USA)

Invited talk

Alpha-cluster structure populated in the resonance reactions induced by rare beams V.Z. Goldberg, G.V. Rogachev Cyclotron Institute, Texas A&M University, College Station, TX 77843, USA The alpha clusterization manifests itself in remarkable and exotic structures in atomic nuclei. In particular, quasi rotational bands of levels with alternative parities and large alpha cluster reduced...
