Abstract

The main source of uncertainties in stellar rate calculations of the rp-process and the competing α p-process is often the lack of knowledge of the resonance states above the p- and α- thresholds and their precise energies. We have started a program to study these resonances in protonrich unstable nuclei via the (p; t) and other neutron-pickup reactions using the high resolution spectrometer Grand Raiden. Here, we are presenting the status of the project and recent results of the ²⁵Al(p;γ) reaction rates based on the analysis of measured ²⁸Si(p,t)²⁶Si spectra.
