The proton-rich nuclei 23Al and 27P were studied using the 24Mg(7Li,8He)23Al and 28Si(7Li,8He)27P reactions, respectively. Several energy levels are observed in each nucleus. The mass excess of 23Al was measured to be 6.773(28) MeV and the mass excess of 27P was measured to be -0.670(41) MeV. The first excited state of 23Al has been resolved from the ground state for the first time at an excitation energy of Ex=0.550(20) MeV. The first excited state of 27P has been measured for the first time at an excitation energy of Ex=1.199(19) MeV. The astrophysical implications of these results for the reaction rates of 22Mg(p,γ)23Al and 26Si(p,γ)27P for the nucleosynthesis of 22Na and 26Al in Ne novae will be discussed.
