2017Ha23: E=69.2 MeV/nucleon 40Ar beam was produced at the Heavy Ion Research Facility in Lanzhou (HIRFL). Target was 182.6 mg/cm2 thick 9Be. Fragments were identified based on energy loss, time-of-flight, and magnetic rigidity on an event-by-event basis, and implanted into a 1500-μm-thick double-sided Si strip detector (DSSD) between two plastic scintillators. Measured half-life of 35Al decay from implant-β decay curve. Comparisons with previous measurements.
