Detection of atomic nuclear reaction products via optical imaging

NUCLEAR REACTIONS ²²Ne(α, n)²⁵Mg, E at Gamow window; ⁹¹Nb(p, γ)⁹²Mo, E at Gamow window; calculated yields, capture and detection efficiency of single reaction product atoms captured in optically transparent solid noble gas, followed by selective identification by laser-induced fluorescence and individual counting via optical imaging to determine the low-yield cross section. Single-atom microscope (SAM) technique.

ATOMIC PHYSICS Li, Be, Na, Al, S, Mg, K, Ca, Zn, Rb, Sr, Mo, Cd, Cs, Ba, Yb, Hg; compiled matrix-isolated absorption and emission atomic spectra of SAM-friendly species.

Quantum-state-selective decay spectroscopy of ²¹³Ra

RADIOACTIVITY ²¹³Ra(α), (EC), (β⁺)[from ¹⁷⁰Er(⁴⁸Ca, 5n), E=4.30 MeV/nucleon using velocity filter SHIP and SHIPTRAP Penning trap at GSI UNILAC facility]; ²⁰⁹Rn(α), (EC), (β⁺)[from ²¹³Ra α decay]; ²¹³Fr(α), (EC), (β⁺)[from ²¹³Ra EC decay]; ²⁰⁹At(α), (EC), (β⁺)[from ²⁰⁹Rn EC decay]; measured Eα, Iα, Eγ, Iγ, αγ-coin, (x ray)α-coin, α and EC+β⁺ branching ratios using TASISpec setup at GSI. GEANT4 simulations. ²⁰⁹Rn; deduced levels, α feedings, γ-ray branching ratios, multipolarity. Comparison with evaluated data, and Nilsson-Strutinsky and shell-model calculations. ²⁰⁹Rn; calculated levels, J, π using shell model with pbpop interaction, total energy surface in (ϵ₂, ϵ₄) plane, and compared with experimental data, and other theoretical calculations.
