Descrição: The 27 Al(p,p`γ) 27 Al nuclear reaction provides the highest cross-sections for gamma-ray emission in aluminium. As a result, the corresponding γ 1 —844 keV and γ 2 —1014 keV gamma lines are commonly used for gamma-ray technique analysis of Al in solid samples. In this work, we report a detailed measurement of the excitation functions for both gamma-ray emissions performed with a HPGe detector placed at an angle of 130º. All the resonances are described in detail by using small energy steps for the incident proton beam from 1490 to 3000 keV, revealing new energy levels of 28 Si. Cross-sections data are validated by comparing experimental values of gamma-ray yields of pure thick Al samples with those calculated by the ERYA-Bulk code, confirming the accuracy of the measurements. Cross-sections and thick target yields obtained in this work are compared with other published data.
