The results of the IS530 experiment at ISOLDE revealed new information concerning several nuclei close to the N approximate to 20 'Island of Inversion' - Mg-34, Al-34, Si-34. The half-life of Mg-34 was found to be three times larger than the adopted value (63(1) ms instead of 20(10) ms). The beta-gamma spectroscopy of Mg-34 performed for the first time in this experiment, led to the first experimental level scheme for Al-34, also showing that the full beta strength goes through the predicted 1(+) isomer in Al-34 [1] and/or excited states that deexcite to it. The subsequent beta-decay of the 1(+) isomer in Al-34 allowed the observation of new gamma lines in Si-34, (tentatively) associated with low-spin high-energy excited states previously unobserved.
