N2 - The location of low-lying states in the very neutron-rich isotope 34Mg has been determined for the first time. In-beam γ-ray spectroscopy was performed using a two-step fragmentation reaction. Two strong γ-lines were observed at 660(10) keV and 1460(20) keV, which are tentatively attributed to the 21/+ → 0g.s./+ and 41/+ → 21/+ transitions in 34Mg, respectively. These tentative assignments lead to a very low energy for the 21/+ state and a large E(41/+)/E(21/+) ratio of about 3.2, in agreement with the expectations for a well deformed isotope.
