In the case of ^(105,106)Tc, the updated Q_(β) 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 ≈ 60 are not a part of the island of shape coexistence around ^(100)Zr_(60).engjournal article2469-9993https://doi.org/10.1103/kksz-prtbhttps://journals.aps.org/prc/abstract/10.1103/kksz-prtbhttps://arxiv.org/abs/2505.15625open access539.1Nuclear-dataFísica nuclear2207 Física Atómica y Nuclear
