ONe novae thermonuclear simulations still show uncertainties in the abundance of the final elements. This comes from the uncertainties that are present in some reaction rates that are considered to be important. One of this is the resonant proton capture on 30P. For decades various experiments tried to restrain the large variations in the reaction rates and many improvements have been made, but the results are still inconclusive. Decay spectroscopy This proceeding paper aims to make a comparison between two indirect methods that can be used to reach the reaction rate of the above-mentioned reaction, by briefly describing the procedure and detection methods used.
