Description
The rapid neutron capture process (r-process) is believed to be responsible
for the creation of a big portion of the elements heavier than iron.
The path of the r-process proceeds in a region of the chart of nuclides where no or little experimental
information is available. While astrophysical scenarios are available, they are all require significant
experimental input from nuclear physics. Relevant experimental quantities constraining r-process
calculations include binding energies, half-lives, neutron capture cross section, most of which are only
provided through theoretical extrapolations. It is thus a long-standing experimental goal to identify
and measure the properties of nuclides which are thought to contribute the most to the observed r-process
abundances. An important region of interest is the A $\approx$ 130 abundance peak, associated to the classical
waiting-point nucleus $^{130}$Cd. The Penning-trap mass spectrometer ISOLTRAP, situated at ISOLDE/CERN, is
primarily dedicated to precision mass measurements of radioactive isotopes, from which their binding energies
can be determined. In a recent experiment, ISOLTRAP measured the masses of the neutron-rich $^{129-131}$Cd isotopes.
In this contribution the current ISOLTRAP setup will be presented as well as the techniques employed for mass
measurements of cadmium isotopes. Furthermore we will discuss the impact of the measured masses on nuclear astrophysics.
