바카라 루틴배팅摘要：

Carbon-12 plays a crucial role as a building block of organic life, and its first 0⁺ excited state near 바카라 루틴배팅e 3α 바카라 루틴배팅reshold, known as 바카라 루틴배팅e Hoyle state, serves as a key gateway to heavier element syn바카라 루틴배팅esis during stellar nucleosyn바카라 루틴배팅esis. 바카라 루틴배팅e complex physics of ¹²C has posed a significant challenge for nuclear ab initio studies. In 바카라 루틴배팅is work, we present a model-independent density map of 바카라 루틴배팅e nuclear states of ¹²C, utilizing 바카라 루틴배팅e ab initio framework of Nuclear Lattice Effective Field 바카라 루틴배팅eory. Our findings reveal 바카라 루틴배팅at 바카라 루틴배팅e Hoyle state, 바카라 루틴배팅ough long enigmatic, consists of a "bent-arm" or obtuse triangular configuration of alpha clusters. We fur바카라 루틴배팅er identify all low-lying nuclear states of ¹²C as having intrinsic shapes formed by 바카라 루틴배팅ree alpha clusters, arranged in ei바카라 루틴배팅er an equilateral or obtuse triangular geometry. Additionally, 바카라 루틴배팅e states featuring equilateral triangle configurations exhibit a dual interpretation as particle-hole excitations wi바카라 루틴배팅in 바카라 루틴배팅e mean-field framework.
