The \(^{24}\)Mg(\(\alpha\),p)\(^{27}\)Al reaction measurement using solenoid spectrometer for nuclear astrophysics (SSNAP)

Abstract

The \(^{24}\)Mg(\(\alpha\),p)\(^{27}\)Al reaction was measured using the solenoid spectrometer for nuclear astrophysics at the University of the Notre Dame to study the astrophysical \(^{24}\)Mg(\(\alpha\),p)\(^{27}\)Al reaction rate. Alpha beams from the 10-MV FN tandem accelerator impinged on \(^{24}\)Mg solid targets which were made using the vacuum evaporation method on \(^{12}\)C foils. A total of 43 beam energies were used. Recoiling protons from the \(^{24}\)Mg(\(\alpha\),p)\(^{27}\)Al reaction were detected using a double-sided position sensitive silicon detector array mounted on the solenoid. Energies, times of flight, and flight distances of particles were measured for particle identification. Protons associated with a wide range of excitation energies \(E_x\) = 12.42–14.44 MeV in \(^{28}\)Si were identified.
