Abstract
γ-ray and fast-timing spectroscopy were used to study levels in Al30 populated following the β- decay of Mg30. Five new transitions and three new levels were located in Al30. A search was made to identify the third 1+ state expected at an excitation energy of ∼2.5 MeV. Two new levels were found, at 3163.9 and 3362.5 keV, that are firm candidates for this state. Using the advanced time-delayed (ATD) βγγ(t) method we have measured the lifetime of the 243.8-keV state to be T1/2=15(4)ps, which implies that the 243.8-keV transition is mainly of M1 character. Its fast B(M1;2+→3+) value of 0.10(3) W.u. is in very good agreement with the USD shell-model prediction of 0.090 W.u. The 1801.5-keV level is the only level observed in this study that could be a candidate for the second excited 2+ state.
