526“…The experimental activity is driven mostly by two motivations: on the one hand, capture reactions are studied with the aim of improving current models of stellar nucleosynthesis of heavy elements. A review of the needs related to nuclear astrophysics and the contribution of the n_TOF program can be found in [1, 2].…”

533“…This gain could feasibly be $10^{(10-12)}$, corresponding to an improvement in sensitivity in the axion-photon coupling, $g_{a\gamma\gamma}$ , of order ${\cal F}^{1/2} \sim 10^{(2.5-3)}$, permitting a practical purely laboratory search to probe axion-photon couplings not previously excluded by stellar evolution limits, or solar axion searches.…”

In particular, the uncertainty of the abundance and the overproduction created by the $rp$-process for the mass A = 99 is demonstrated by reducing the uncertainty of the proton-separation energy of $^{100}$In $S_{p}(^{100}$In) by a factor of 2.5.…”
