Abstract

This study explores the investigation of negative parity states in the odd-A nucleus ⁷¹Ga. Specifically, we focus on analyzing E2 strengths connecting the initial two negative parity states (3/2⁻) to the first two negative parity states (7/2⁻). Our findings reveal distinct characteristics of these states, with the first 3/2⁻ state predominantly exhibiting ground band features (g), while the first 7/2⁻ state is associated with excited band properties (e). Through a comprehensive analysis of negative parity states, we establish a clear connection between the nature of these states and their corresponding E2 transition strengths.

This investigation contributes significant insights into the behaviour of negative parity states in odd-A nuclei, offering a nuanced perspective on the distinctive features of ground and excited bands in ⁷¹Ga. Our findings advance the understanding of nuclear structure, providing a valuable contribution to the broader field of nuclear physics.

71Ga负宇称态的结构

本研究探讨了奇a核71Ga的负宇称态。具体来说，我们重点分析了连接初始两个负宇称态（3/2−）和前两个负宇称态（7/2−）的E2强度。我们的发现揭示了这些状态的明显特征，第一个3/2 -状态主要表现出基带特征(g)，而第一个7/2 -状态与激发带特性有关(e)。通过对负宇称态的综合分析，我们建立了这些态的性质与其对应的E2跃迁强度之间的明确联系。这项研究对奇a核负宇称态的行为有重要的见解，为71Ga的基带和激发带的独特特征提供了细致入微的视角。我们的发现促进了对核结构的理解，为更广泛的核物理领域提供了宝贵的贡献。
