Spectral Structure Analysis of Nuclei ¹⁴C, ^14,15N, and ^14-18O Near Double Magic Nucleus ¹⁶O by Shell Model Calculations

According to three different interactions of YSOX, WBT and WBP, the spectral structure of nuclei ¹⁴C, ^14,15N, and ^14-18O near double magic nucleus ¹⁶O are analyzed by shell model calculations. The good effects have been found in spectral structure of these nuclei after reconsidering shell interaction. The large data analysis between these different shell model interactions and experiment also revealed the limitations of these existing interactions in this nuclei region, for example the large difference between theory and experiment, the reversed order of states and so on, which brings the further motivations of modifying shell model Hamiltonians.
