论文摘要
在目前的工作中，最近可用的$^{67} $的不同频段的实验数据为[phys。修订版C {\ bf 98}，024313（2018）]在全$ f_ {5/2} pg_ {9/2} $模型空间中使用JUN45和JJ44B有效交互。 $ e $ - $ e_ {rot} $能量与旋转的变化显示出有关频带终止的有用信息。我们还报告了$^{67} $的电磁过渡概率，四极矩和磁矩。除某些暂定的高速旋转状态外，结果与可用的实验数据非常吻合。$ 29/2^+$ - $ 45/2^+$描述了$ g_ {9/2} $的三个粒子，而$ 47/2^+$和$ 51/2^+$的$ g_ nate $ g_ g_ {9/2} $ {9/2} $ {9/2}}}。壳模型结果对应于九个暂定状态，例如$ 41/2_1^+$和$ 45/2_1^+$在band-1b中； $ 41/2_2^+$和$ 45/2_2^+$在band-1a中; $ 43/2_2^+$，$ 47/2_2^+$和$ 51/2_1^+$ in Band-2a;报告并讨论了$ 43/2_1^+$和$ 47/2_1^+$。
In the present work, recently available experimental data for different bands of $^{67}$As [Phys. Rev. C {\bf 98}, 024313 (2018)] have been interpreted within the framework of the shell model in full $f_{5/2}pg_{9/2}$ model space using JUN45 and jj44b effective interactions. The variation of $E$ - $E_{rot}$ energy versus spin for different bands is shown to obtain useful information about band termination. We have also reported the electromagnetic transition probabilities, quadrupole and magnetic moments of $^{67}$As. Except for some tentative high-spin states, the results are in good agreement with the available experimental data.The states $29/2^+$-$45/2^+$ are described by three particles in $g_{9/2}$, while $47/2^+$ and $51/2^+$ states are described by five particles in $g_{9/2}$. The shell model results corresponding to nine tentative states such as $41/2_1^+$ and $45/2_1^+$ in band-1b; $41/2_2^+$ and $45/2_2^+$ in band-1a; $43/2_2^+$, $47/2_2^+$ and $51/2_1^+$ in band-2a; $43/2_1^+$ and $47/2_1^+$ in band-2b are reported and discussed.
