E0 transitions in the  -unstable nucleus¹²⁴Te

Investigation of shape coexistence in 118–128Te isotopes

“…The investigations of the experimental energy spectra which have done in Refs. [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25], suggest the Te isotopes as the empirical evidences in transitional region between the spherical, U (5) or vibrational, and deformed, SO (6) or  -unstable, limits. These results suggest that the normal vibrational states are mixed with deformed intruder states and consequently, one can use a U(5)↔SO (6) transitional…”

“…Also, we have compared our results with different analyses such as Refs. [10][11][12][13][14][15][16][17][18][19][20][21][22][23] to appreciate the advantages (or disadvantages) of different theoretical methods. These nuclei have not considered in other theoretical studies completely but for some of them which we have found similar counterparts, our results which have derived via more parameters (as compared to the standard IBM shape-phase transition approaches [35][36][37][38][39][40]) explore more exact results.…”

Study of shape coexistence in the 180−190Hg isotopes by SO(6) representation of eigenstates

“…If these excitations are proton excitations combined with the neutron degree of freedom appearing on both sides of the Z=50 closed shell, such as condition which are available for Te isotopes, it is a natural step to suggest that low-lying extra 0 + excitations will also show up in the even-even nuclei in between. Because the Te isotopes with a large number of valence neutrons are situated near to the  -stability line, they could be studied [62][63][64][65].…”
