Type I X-ray bursts are thermonuclear runaways that occur on the surface of neutron stars in binary systems with low-mass companions. These systems, in some cases, host the so-called rapid proton capture process (rp–process) [1,2]. Under high temperature (T ~2 GK) and density (rho> 1E5 g/cm3) conditions in the burning layer, the nuclear reaction network of the rp- process runs close to the...

A complete understanding of the synthesis of the elements is one of the main outstanding questions in nuclear astrophysics. A number of nucleosynthesis processes are known and to a reasonable extent account for much of the observed solar abundances of nuclei. However, there are a number of elements that can only be produced via processes involving proton rich nuclei. The rapid...

2. Mass measurements of exotic nuclides along the rp-process path at SHIPTRAP

The masses of proton-rich nuclides in the element range from Sr to Tc were measured with the Penning trap mass spectrometer SHIPTRAP [1] at GSI. These nuclei were produced in the fusion-evaporation reaction 36Ar + 54Fe at energies of 5.0 and 5.9 MeV/u and separated by the velocity filter SHIP [2]. Their masses were measured with relative accuracies ranging from 5·10-8 to 2·10-7. The masses...
