摘要:

本文报道了在$^{68}$ Ni中观察到的一种新的同分异构态。我们认为,在第一个2 $^+$态以上168(1)keV处新观察到的态是穿过Z=28的主要壳层间隙的$π(2p-2h)$ 0 $^{+}$态。与理论计算的比较表明,一个纯质子入侵者配置和推导出的低洼结构,这个关键的核表明一个可能的形状共存的情况下,涉及一个高度变形的状态。

英文摘要:

We report on the observation of a new isomeric state in $^{68}$Ni. We suggest that the newly observed state at 168(1) keV above the first 2$^+$ state is a $π(2p-2h)$ 0$^{+}$ state across the major Z=28 shell gap. Comparison with theoretical calculations indicates a pure proton intruder configuration and the deduced low-lying structure of this key nucleus suggests a possible shape coexistence scenario involving a highly deformed state.
