The low-energy 19F(p,)16O reaction has significant implications for nuclear astrophysics. The 19F(p,
)16O reaction occurs via three channels: (p,
), (p,
), and (p,
). At lower temperatures, below 0.15 GK, the (p,
) channel is the dominant contributor of the reaction. The 19F(p,
)16O reaction cross section in the energy range of 400–900 keV was studied in this work. Recent data in the literature reveals a roughly 1.4 increase compared to prior findings reported in the NACRE (Nuclear Astrophysics Compilation of REactions) compilation. Therefore, we present new additional result of the study published in EPJA [22] employing a silicon strip detector array (LHASA - Large High-resolution Array of Silicon for Astrophysics). The anguar distributions, the reaction cross sections and the astrophysical S-factors of the (p,
) channel were obtained through this experiment. Our findings resolve the discrepancies that exist between the two previously available data sets in the literature.
