Spectroscopy around N = 20 shell closure: $\beta$–n decay study of $^{35}$Al

Abstract : An experimental spectroscopic investigation of $^{35}$Al has been performed. The delayed neutron and $gamma$ spectra, following the $\beta$ decay of $^{35}$Al, have been measured using the delayed neutron detector array TONNERRE coupled with high efficiency $\gamma$ 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 $\beta$–$\gamma$–n coincidences eight new levels above the neutron separation energy in $^{34}$Si were for the first time observed.
