Imaging recoil ions from optical collisions between ultracold, metastable neon isotopes
Abstract
We present an experimental scheme which combines the well established method of velocity-mapimaging, with a cold trapped metastable neon target. The device is used for obtaining the branching ratios and recoil-ion energy distributions for the penning ionization process in optical collisions of ultracold metastable neon. The potential depth of the highly excited dimer potential is extracted and compared with theoretical calculations. The simplicity to construct, characterize and apply such a device, makes it a unique tool for the low-energy nuclear physics community, enabling opportunities for precision measurements in beta- and beta-delayed-neutron decays of cold, trapped, short-lived radioactive isotopes.
