“…The B (E2) data of Pd [102][103][104][105][106][107][108][109][110][111][112] and Ru 96-102 nuclei were examined [12][13][14]. Several vibrational-gamma soft properties IBM calculations have been reported that dealt with the IBM and IVBM models [15][16][17][18][19]. The aim of the present work is to interpret the collective behavior of yrast state of 124 Te nucleus by D-G, IBM-1, BM, and IVBM models.…”

The exact eigenenergies of the T4c = [cc][cc], T 4b = [bb][ bb ], and T 2[bc] = [bc][ bc] tetraquarks are calculated within the extended transitional Hamiltonian approach, in which the so-called Bethe ansatz within an infinite-dimensional Lie algebra is used. We fit the parameters appearing in the transitional region from phenomenology associated with potential candidates of tetraquarks. The rotation and vibration transitional theory seems to provide a better description of heavy tetraquarks than other attempts within the same formalism. Our results indicate that the pairing strengths are large enough to provide binding; an extended comparison with the current literature is also performed.

Random matrix theory (RMT) is used to provide a measure of the chaoticity (q) of calculated results for the spectra for various Cd isotopes. The goal is to gain a better understanding of the internal dynamics in play; namely, whether it tracks with regular or irregular (chaotic) behavior as determined through an RMT analyses of calculated spectra. The basis-state configurations used to determine the spectra includes all positive, negative, natural (J π = 1 − , 2 + , . . .), and unnatural parity configurations (J π = 0 − , 1 + , 2 − , . . .), unless suppressed for comparative purposes. The results show that when intruder-state configurations are in play, regular behavior emerges, but when not in play, chaotic behavior seems to dominate the dynamics.
