dc.description.abstractThe masses of the astrophysically relevant nuclei 25Al and 30P have been measured with a Penning trap for the first time. The mass-excess values for 25Al (∆ = −8915.962(63) keV) and 30P (∆ = −20200.854(64) keV) obtained with the JYFLTRAP double Penning trap mass spectrometer are in good agreement with the Atomic Mass Evaluation 2012 values but ≈5-10 times more precise. A high precision is required for calculating resonant proton-capture rates of astrophysically important reactions 25Al(p, γ) 26Si and 30P(p, γ) 31S. In this work, Q(p,γ) = 5513.99(13) keV and Q(p,γ) = 6130.64(24) keV were obtained for 25Al and 30P, respectively. The effect of the more precise values on the resonant protoncapture rates has been studied. In addition to nuclear astrophysics, the measured QEC value of 25Al, 4276.805(45) keV, is relevant for studies of T = 1/2 mirror beta decays which have potential to be used to test the Conserved Vector Current hypothesis.
