Description
Nuclear masses are fundamental observables that give insight into nuclear structure, fundamental interactions, and astrophysics. Pairing gaps are an experimental observable that can be extracted from nuclear mass data and can show exotic nuclear behavior, especially for odd-even staggering and pairing effects. These pairing gaps can also provide information about nuclear deformation and the existence of the exotic state of matter known as spin-triplet pairing, especially near the $N=Z$ and $A\approx130$ region.
Multiple-Reflection Time of Flight Mass Spectrometry (MR-TOF-MS) provides high mass separation power in a short amount of time by bouncing ions between electrostatic mirrors. This increases the flight path of trapped ions, allowing ions of different mass but injected with the same energy to separate. The high mass resolving powers and short storage times have contributed to MR-TOF devices becoming common for beam purification and mass spectrometry in Rare-Isotope-Beam and accelerator facilities around the world. To search for the nucleon spin triplet pairing, we used the TRIUMF Ion Trap for Atomic and Nuclear science (TITAN) MR-TOF-MS to measure several samarium, europium, cerium, and lanthanum isotopes in the specified region.
