The low-lying level structure of ${}^{63}\mathrm{V}$ was studied for the first time by the inelastic proton scattering and the proton knock-out reaction in inverse kinematics. The comparison of the newly observed $\gamma$-ray transitions at 696(8) keV and 889(16) keV with our shell-model calculations using the Lenzi-Nowacki-Poves-Sieja interaction established two excited states proposed to be the first $11/2^{-}$ and $9/2^{-}$ levels. The $(p,p^{\prime })$ excitation cross sections were analyzed by the coupled channel formalism assuming pure quadrupole as well as quadrupole+hexadecapole deformations. This resulted in large deformation parameters placing ${}^{63}\mathrm{V}$ in the island of inversion located below ${}^{68}\mathrm{Ni}$.

V63在N=40反演岛的首次光谱研究

低层结构 ${}^{63}\mathrm{伏}$首次通过非弹性质子散射和逆运动学中的质子敲除反应进行了研究。新观察到的比较$\gamma$我们使用 Lenzi-Nowacki-Poves-Sieja 相互作用的壳模型计算在 696(8) keV 和 889(16) keV 处的 -射线跃迁建立了两个被提议为第一个的激发态 $11/2^{-}$ 和 $9/2^{-}$水平。这$(磷,{磷}^{\prime })$假设纯四极杆以及四极杆+十六极杆变形，通过耦合通道形式分析激发截面。这导致大变形参数放置${}^{63}\mathrm{伏}$在位于下方的反转岛中${}^{68}你$.
