β-delayed particle emission from 21Mg

. The β -delayed particle emission from 21 Mg was studied at the Radioactive Ion Beam Line in Lanzhou (RIBLL1). Silicon array and high-purity germanium (HPGe) detectors were used to detect the charged particles and γ -rays emitted from the decay. Half-life time of 21 Mg was determined to be 121.9(6)...

Description
Summary:. The β -delayed particle emission from 21 Mg was studied at the Radioactive Ion Beam Line in Lanzhou (RIBLL1). Silicon array and high-purity germanium (HPGe) detectors were used to detect the charged particles and γ -rays emitted from the decay. Half-life time of 21 Mg was determined to be 121.9(6) ms. New levels (5.639(26) MeV and 6.644(34) MeV) in the nucleus 21 Na were observed. An improved proton spectrum coincident with γ -rays at 1.633 MeV was obtained. A new partial decay scheme was constructed based on the present measurement.
