CISE

The acronym CISE stands for Chemically Isobaric SEparation. Our goal the to develop this technique to catch doubly magic tin. The isotope tin-100 which has 50 neutron and 50 protons is located near the proton drip-line. It is accessible through fusion-evaporation reactions with relatively high cross-sections. However, in these reaction a large amount of un-wanted by-products are produced such as proton-rich isotopes of silver, indium, and cadmium.

Therefore, we want to develop a fast chemical separation technique to suppress un-wanted by-products and in order to prepare tin-100 for precision mass measurements. 

With the help of the mechanical and electronic workshop of PARTREC, we designed and build a setup to develop offline the chemical separation techniques. Parts of the setup can be later implemented in the SHIPTRAP facility to apply chemical separation. 

We are grateful for funding through an NWO-natuurkunde Projectruimte grant 

(projectnumber:680-91-103). 

The Penning trap facility SHIPTRAP is coupled to the velocity filter SHIP at GSI, Darmstadt, Germany. This unique setup allows precision mass measurements of the heaviest atomic nuclei that are accessible through nuclear fusion evaporation reactions.
