| 1 | Spectroscopy of Low-lying States in Odd-Z Odd-A Nuclei Beyond Lead显示文摘Low-lying states in odd-Z odd-mass nuclei at the proton drip-line beyond lead have recently been studied through fusion-evaporation reactions using a gas-filled recoil separator. Isomeric 1/2+and13/2+states have been observed in odd-mass astatine and francium nuclei. The systematic behaviour of the level energies of these states have been studied and a similarity between the 1/2+state in astatine and francium has been found. Furthermore, the 13/2+state has been observed in the francium nuclei with an oblate behaviour suggesting a coupling of the i13/2proton to the 2p- 2h intruder excitation. | U.Jakobsson J.Uusitalo K.Auranen H.Badran B.Cederwall D.M.Cox T.Grahn P.T.Greenlees R.Julin S.Juutinen A.Herzán J.Konki M.Leino M.Mallaburn J.Pakarinen P.Papadakis J.Partanen P.Rahkila M.Sandzelius J.Sarén C.Scholey J.Sorri S.Stolze | 2016 | 原子核物理评论2016，33，2： | 0 |
