Abstract:

In this paper we present the first high-resolution laser spectroscopy results obtained at the GISELE laser laboratory of the GANIL-SPIRAL2 facility, in preparation for the first experiments with the S^3-Low Energy Branch. Studies of neutron-deficient radioactive isotopes of erbium and tin represent the first physics cases to be studied at S^3. The measured isotope-shift and hyperfine structure data are presented for stable isotopes of these elements. The erbium isotopes were studied using the 4𝑓^12 6𝑠^2 ^3𝐻_6 β†’ 4𝑓^12 (^3𝐻)6𝑠6𝑝 𝐽 = 5 atomic transition (415 nm) and the tin isotopes were studied by the 5𝑠^2 5𝑝2(^3𝑃_0) β†’ 5𝑠^2 5𝑝6𝑠(^3𝑃_1) atomic transition (286.4 nm), and are used as a benchmark of the laser setup. Additionally, the tin isotopes were studied by the 5𝑠^2 5𝑝6𝑠(^3𝑃_1) β†’ 5𝑠^2 5𝑝6𝑝(^3𝑃_2) atomic transition (811.6 nm), for which new isotope-shift data was obtained and the corresponding field-shift 𝐹812 and mass-shift 𝑀812 factors are presented.
