Description
One of the compelling areas of focus in nuclear and atomic physics are isotopes and isomers of different atoms. Many different isotopes are highly desired for experimental studies; however, accessing them is challenging with existing methods. A novel method that involves antiprotonic atoms has been suggested in [1]. In this method, the creation of isotopes is achieved by forcing the annihilation of the antiproton ($\bar{\rm{p}}$) inside the antiprotonic atom [2]. The annihilation of $\bar{\rm{p}}$ with one of the nucleons inside the nuclei produces mainly pions, from which some are captured by the remainder nucleus, leading to nuclear fragmentation.
This production path provides a significant yield of short-lived isotopes. Furthermore, the method requires the entire process to be executed directly inside an ultra-high vacuum system within an electromagnetic trap, allowing for the possibility of re-trapping previously unavailable atomic species, immediately upon their production with ns time precision.
The focus of this contribution is a further study conducted of the GEANT4 simulation data. We suggest a better assessment of the trappable fragments from the antiproton-induced fission. We also propose an advanced technique for obtaining access to some of the most intangible isotopes of interest and their isomers.
