Thick-target yields were obtained from activation by the online measurement of the decay of the 30P reaction product, using the recently developed Gamma-detection Array for Reaction Yield measurements. The results show good agreement with existing data and confirm the newest thick-target yields at low energies. Direct 27Al(α,nγ)30P γ-yields were measured in order to address (α, n) branches to excited states in 30P. The angular dependence of the emitted prompt γ rays was investigated, revealing significant differences as a function of angle with respect to the beam direction. The results provide benchmark data for future (α, n) yield studies using online activation measurements and prompt γ-ray detection.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal article1879-0895https://dx.doi.org/10.1016/j.radphyschem.2026.113815https://www.sciencedirect.com/science/article/pii/S0969806X26002252open access52-33539.1Thick target yieldGamma ray spectroscopy(α, n) reactionsPrompt-gamma raysAstrofísicaFísica nuclear21 Astronomía y Astrofísica2207.90 Física Nuclear Experimental Bajas Energías
