| 1 | Revisit to Two-Proton Radioactivity of 19Mg and Observation of Two-Proton Decay of 30Ar显示文摘An experiment aimed to investigate the two-proton(2p) decay of the previously unknown nucleus ^(30)Ar was performed at GSI. By tracking the decay products in-flight with silicon micro-strip detectors, the 2p decays of ^(30)Ar were observed for the first time. For the calibration purpose, 2p decays of ^(19)Mg were also remeasured by tracking the coincident ^(17)Ne+p+p trajectories. By comparing the measured angular p-17 Ne correlations with those obtained from the corresponding Monte Carlo simulations,the simultaneous 2p decay of ^(19)Mg ground state and the sequential 2p emission of several known excited states of ^(19)Mg were confirmed. One new excited state in ^(19)Mg and two new excited states in ^(18)Na were observed. | 徐晓栋 I.Mukha L.Acosta E.Casarejos A.A.Ciemny W.Dominik J.Duénas-Díaz V.Dunin J.M.Espino A.Estradé F.Farinon H.Geissel A.Fomichev T.A.Golubkova A.Gorshkov L.V.Grigorenko Z.Janas G.Kamiński O.Kiselev R.Knbel S.Krupko M.Kuich Yu.A.Litvinov G.Marquinez-Dur'an I.Martel C.Mazzocchi C.Nociforo A.K.Ord'uz M.Pfützner S.Pietri M.Pomorski A.Prochazka S.Rymzhanova A.M.S'anchez-Benítez C.Scheidenberger P.Sharov H.Simon B.Sitar R.Slepnev M.Stanoiu P.Strmen I.Szarka M.Takechi Y.K.Tanaka H.Weick M.Winkler J.S.Winfield | 2016 | 原子核物理评论2016，33，2： | 1 |
