The energies of the and transitions, observed here for the first time, indicate a deformed 62Ti ground state. These energies are increased compared to the neighboring 64Cr and 66Fe isotones, suggesting a small decrease of quadrupole collectivity. The present measurement is well reproduced by large-scale shell-model calculations based on effective interactions, while ab initio and beyond mean-field calculations do not yet reproduce our findings. The shell-model calculations for 62Ti show a dominant configuration with four neutrons excited across the gap. Likewise, they indicate that the island of inversion extends down to , disfavoring a possible doubly magic character of the elusive 60Ca.1 p.application/pdfengcc-by (c) SEASTAR Collaboration et al., 2019http://creativecommons.org/licenses/by/4.0/IsòtopsEspectrometria de raigs gammaIsotopesGamma ray spectrometryinfo:eu-repo/semantics/article6976302024-09-17info:eu-repo/semantics/openAccess
