Spectroscopy around N = 20 shell closure: β–n decay study of 35Al

An experimental spectroscopic investigation of 35Al has been performed. The delayed neutron and γ spectra, following the β decay of 35Al, have been measured using the delayed neutron detector array TONNERRE coupled with high efficiency γ detectors. A detailed analysis of such spectra allows one to extract the level schemes of its daughters. These levels are compared with the few previously existing data and shell-model calculations. Based on triple β–γ–n coincidences eight new levels above the neutron separation energy in 34Si were for the first time observed.
