Measurement of theH2(d,p)H3reaction at astrophysical energies via

First Measurement of the 19F(α, p)22Ne Reaction at Energies of Astrophysical Relevance

“…The THM wasdiscussed for the first time in Baur (1986) andSpitaleri (1991. It has been successfully applied to several fundamental astrophysical problems, such as primordial nucleosynthesis (Rinollo et al 2005;Pizzone et al 2014;Tumino et al 2014;Li et al 2015), thelithium problem (Pizzone et al 2005b;Lamia et al 2012Lamia et al , 2013, light elementdepletion (Spitaleri et al 2014;Lamia et al 2015), AGB stars (La Cognata et al 2009;Palmerini et al 2013), and novanucleosynthesis (Sergi et al 2015). Recently, the method has proven suitable for measurements involving radioactive ion beams (Cherubini et al 2015;Pizzone et al 2016) and neutrons (Gulino et al 2013), thus proving its wide applicability.…”

“…The experimental setup was installed in the nuclear reaction chamber at the R60 beam line terminal as shown in Figure 2. The 6 Li 2+ beam at 9.5 MeV [13] and 11 MeV provided by the HI-13 tandem accelerator was used to bombard a deuterated polyethylene target CD 2 . The thickness of the target is about 160µg/cm 2 .…”

The Trojan Horse Method for nuclear astrophysics and its recent applications

“…However, it must be stressed here that the TH S(E)-factor determination requires a normalization procedure to the available direct measurements performed at higher energies, thus rendering the THM a complementary experimental technique for nuclear astrophysics aimed at reaching the ultra-low energy region of interest for astrophysical applications. THM has been used in studying several problems, ranging from BBN [7], light element burning reactions [8][9][10][11][12], CNO reactions [13][14][15], explosive nucleosynthesis involving RIB [16,17] and removing/producing neutron reactions [18,19].…”

“…In particular, both the s and d state wave functions have been calculated by using the exact form and the asymptotic one, their shape being the one shown in the left panel of Fig.1. In order to evaluate the impact on THM data, we have introduced the d state contribution in the THM analysis of [23] and we found a maximum variation of about 0.5% on the absolute value of the S(0) for the 11 B+p reaction.…”

“…Energy resolution effects on the relative E cC energy can be evaluated via the standard errors propagation theory, taking into account both energy and angular resolution due to the adopted experimental setup. For instance, in the case of the 11 B+p reaction discussed in [22,23], this has been evaluated to be ∼40 keV;…”
