摘要：

A new unbound level at Ex = 2833±7 keV has been found in 21Na via the reaction 20Ne (d, nγ)21Na. The state decays mostly by γ-rays to the 1723 and 332 keV levels. This might be the missing Jπ = 9 2+ level. From n-γ correlation measurements, the spins of 21*Na = 331.9±0.5, 1723±4 and 2432±2 keV are found to be 5 2 or 3 2, ≦ 7 2 and ( 1 2), respectively. Branching ratios and some mixing ratios are reported. The level schemes of the mirror nuclei 21Na and 21Ne are compared. © 1969.
