Description
The 34Al β decay was studied at the CERN on-line mass separator ISOLDE. Gamma-ray singles, β-γ, and β-γ-γ coincidence measurements, were registered with two 80% Ge detectors. A 34Al β-decay scheme to 34Si bound states is established. The first level scheme in 34Si includes three levels at 3327.7 ± 0.5, 4257.3 ± 0.4 and 4382.7 ± 0.7 keV with respectively a Jπ assignment of 2+, 3- and (4,5)-. The 34Si level scheme is consistent with the assignment of Jπ=4- for the34Al ground state. The value of P1n=0.27(5) has been deduced for the β-delayed 1n emission of 34Al. The 34Si level scheme is found to agree with the present shell-model predictions. In the resulting picture, 34Si appears to be a new doubly magic nucleus
