Description
Research in the field of superheavy elements (SHE) has gained quite a significant progress with introduction of doubly magic 48Ca beams into the experimental campaigns aimed to reach the shores of the island of stability [1]. As known cross-sections of reactions, leading to SHE is limited to pico-barns thus requiring high beam intensities (now available within an order of magnitude less than 1 pµA) and experimental sessions lasting for months.
Admitting high importance of 48Ca beams in SHE research one should take into consideration that modern and future experiments in that field require production of beams of other elements [2], i.e. 50Ti, 46Ti. Beams of such nuclides as 54Cr, 58Fe, 64Ni and some others are also attracting attention. As stated higher, experiments make necessary long-term stability and high concentration of substance (vapor pressure), containing the nuclide, in the ion source. Some approaches to production and regeneration of such compounds as well as collation of them was performed.
