Mass measurements near the Z = N line with JYFLTRAP

Masses of nuclides involved in astrophysical rp and νp processes have to be known precisely in order to model these processes reliably. Mass excesses for 90 ground state and 8 isomeric states of neutron-deficient nuclides have been determined with a precision of better than 10 keV with the JYFLTRAP double Penning trap mass spectrometer at the Ion-Guide Isotope Separator On-Line facility in Jyvaeskylae. Highlights of the measurements related to nuclear astrophysics are given. Some of the measured isomers, such as 53Com, 90Tcm, and 95Pdm, and implications for the excitation energy of the 21+ isomer in 94Ag are briefly discussed.
