Isotope shift and search for metastable superheavy elements in astrophysical data
Abstract
Spectral lines belonging to the short-lifetime heavy radioactive elements up to Es (=99) have been found in the spectra of the Przybylski's star. We suggest that these unstable elements may be decay products of a "magic" metastable nucleus belonging to the the island of stability where the nuclei have a magic number of neutrons . The laboratory-produced nuclei have a significantly smaller number of neutrons. To identify spectra of the isotopes of these nuclei and their neutron-reach superheavy decay products in astrophysical data we calculate the isotope shift which should be added to the laboratory - measured wavelenghs. The results for the isotopic shifts in the strongest optical electromagnetic transitions in No, Lr, Nh, Fl,and =120 elements are presented.
