Isotope shift and search for metastable superheavy elements in astrophysical data

Isotope shift and search for metastable superheavy elements in astrophysical data We explore a possibility that astrophysical data may contain spectra of metastable nuclei belonging to the island of stability where the nuclei have a magic number of neutrons of N=184. The laboratory-produced nuclei have a significantly smaller number of neutrons. To identify spectra of the N=184 isotopes of these nuclei and their neutron-rich superheavy decay products in astrophysical data we calculate the isotope shift which should be added to the laboratory-measured wavelengths. The results for the isotope shifts in the strongest optical electromagnetic transitions in No, Lr, Nh, Fl, and Z=120 elements are presented. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review A American Physical Society (APS)

The laboratory-produced nuclei have a significantly smaller number of neutrons. To identify spectra of the N=184 isotopes of these nuclei and their neutron-rich superheavy decay products in astrophysical data we calculate the isotope shift which should be added to the laboratory-measured wavelengths. The results for the isotope shifts in the strongest optical electromagnetic transitions in No, Lr, Nh, Fl, and Z=120 elements are presented.
