Vikas Kumar, Praveen C. Srivastava

摘要:

在本工作中,最近获得的$^{67}$ As不同谱带的实验数据[Phys. Rev. C { \bf 98},024313(2018)]已在全$f_{5/2}pg_{9/2}$模型空间中使用JUN 45和jj 44 b有效相互作用的壳模型框架内进行了解释。$E$ - $E_{rot}$的能量与自旋不同的频带的变化,以获得有用的信息带终止。我们还报道了$^{67}$ As的电磁跃迁几率、四极矩和磁矩。在$g_{9/2}$中,$29/2^+$-$45/2^+$态用三个粒子描述,$47/2^+$和$51/2^+$态用五个粒子描述.本文报道并讨论了9种实验态的壳模型结果,它们是:带1b的$41/2_1^+$和$45/2_1^+$,带1a的$41/2_2^+$和$45/2_2^+$,带2a的$43/2_2^+$、$47/2_2^+$和$51/2_1^+$,带2b的$43/2_1^+$和$47/2_1^+$。

英文摘要:

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.
