Probing the quantum phase transition near <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow> <mml:mi>N</mml:mi> <mml:mo>≈</mml:mo> <mml:mn>60</mml:mn> </mml:mrow> </mml:math> via mass measurements of technetium isotopes
The masses of neutron-rich $^{104--106}\mathrm{Tc}$ isotopes were measured using the JYFLTRAP double Penning trap and found to deviate from the Atomic Mass Evaluation 2020 by $\ensuremath{-}79(25)$, 40(12), and 94(41) keV, respectively. In the case of $^{105,106}\mathrm{Tc}$, the updated ${Q}_{\ensuremath{\beta}}$ values are in agreement with a previous JYFLTRAP measurement, disagreeing with the values from the mass evaluation. The new mass values result in a more linear trend in two-neutron separation energies indicating that technetium ($Z=43$) isotopes around $N\ensuremath{\approx}60$ are not a part of the island of shape coexistence around $^{100}\mathrm{Zr}_{60}$.
