Long-lived isotopes of plutonium were studied using two complementary techniques, high-resolution resonance ionization spectroscopy (HR-RIS) and collinear laser spectroscopy (CLS). Isotope shifts have been measured on the 5f67s27F0→5f56d27s(J=1) and 5f67s27F1→5f67s7p(J=2) atomic transitions using the HR-RIS method and the hyperfine factors have been extracted for the odd mass nuclei 239,241Pu. CLS was performed on the 5f67s8F1/2→J=1/2(27523.61cm−1) ionic transition with the hyperfine A factors measured for 239Pu. Changes in mean-squared charge radii have been extracted and show a good agreement with previous nonoptical methods, with an uncertainty improvement by approximately one order of magnitude. Plutonium represents the heaviest element studied to date using collinear laser spectroscopy.

Efficient, high-resolution resonance laser ionization spectroscopy using weak transitions to long-lived excited states
Groote, R. P. de; Verlinde, M.; Sonnenschein, Volker; Flanagan, K. T.; Moore, Iain (American Physical Society, 2017)Laser spectroscopic studies on minute samples of exotic radioactive nuclei require very efficient experimental techniques. In addition, high resolving powers are required to allow extraction of nuclear structure ... -
