“…These effects are well-known in the neutron-rich isotopes with masses A ∼ 100 [4,5]. Several experimental [6][7][8] and theoretical [4,5,9,10] studies are ongoing to better characterize the structural evolution of the ground and excited states in this mass region. The neutron-rich odd-odd 98 Y (N = 39, Z = 59) nucleus is of particular interest owing to its position on the border of a ground-state shape change.…”

The nuclear structure of the odd-odd nucleus 98 Y has been re-investigated by observing prompt γ rays emitted following the proton-induced fission of a 238 U target, using the JUROGAM-II multidetector array. New highspin decays have been observed and placed in the level schemes using triple coincidences. The experimental level energies and γ-decay patterns are compared to GICM and QPRM calculations, assuming that this neutronrich N = 59 isotone is spherical at low energies and prolate deformed at intermediate spins.

“…The A ∼ 100 region near Zr is well-known for a dramatic shape change at N = 60 [19]. However, in the molybdenum isotopes the change is more gradual, as evidenced by changes in nuclear charge radii [20]. The transition near 100 Mo is characterized by shape-coexistence behavior, with particular consequences for the population patterns observed in (p, t) and (t, p) reactions.…”

“…Any statistical errors related to the fits of the optical spectrum do not contribute at this scale. The fractional systematic uncertainty of the voltages due to the readback of the RFQ and scanning voltage of the light collection region corresponds to 0.1% [35]. The effect of a systematic uncertainty arising due to the voltage readback is considered to be ∼0.003 5 cm −1 .…”

“…According to [35,36], V RFQ /V RFQ = 10 −3 and δV LCR /δV LCR = 10 −4 , respectively. The bias of the RFQ is read out on a scan-byscan basis via a 1 : 10 4 resistor stack [36] and its weighted mean is used.…”

High-resolution laser spectroscopy of long-lived plutonium isotopes Voss, Annika; Sonnenschein, Volker; Campbell, P.; Cheal, B.; Kron, T.; Moore, Iain; Pohjalainen, Ilkka; Raeder, S.; Trautmann, N.; Wendt, K.Voss, A., Sonnenschein, V., Campbell, P., Cheal, B., Kron, T., Moore, I., . . . Wendt, K. (2017 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 5f 6 7s 2 7 F 0 → 5f 5 6d 2 7s (J = 1) and 5f 6 7s 2 7 F 1 → 5f 6 7s7p (J = 2) atomic transitions using the HR-RIS method and the hyperfine factors have been extracted for the odd mass nuclei 239,241 Pu. CLS was performed on the 5f 6 7s 8 F 1/2 → J = 1/2 (27 523.61 cm −1 ) ionic transition with the hyperfine A factors measured for 239 Pu. 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.
