“…This is in agreement with the systematics of the Hg region and the A=190 and with the theoretical predictions [10]. Several calculations [12,13] have been performed to identify the spin of the state that forms the band head of the superdeformed band, leading to mismatching results. A new experiment was performed in order to obtain direct measurements of the lifetimes of the excited states in 189 Hg.…”

The mercury isotopic chain is depicted as one of the best fields to observe many phenomena related to collectivity evolution as, for instance, shape transition, shape coexistence or shape staggering. In this context, the 189Hg presents several interesting aspects and is still relatively unexplored. The nucleus has been studied at the Laboratori Nazionali di Legnaro using a fusion-evaporation reaction and the γ rays emitted have been detected by the GALILEO array, coupled with Neutron Wall and the GALILEO plunger. The presorting and the preliminary results are presented.

“…However, when we plot J (2) against ω, a rapid rise with ω is displayed by all the SD bands in Hg isotopes (see Figs. [5][6][7][8]. It is also noticed from Figs.…”

“…This is due to the undiscovered linking transitions among the SD and the normal deformed (ND) bands. The spin determination has been achieved by taking theoretical models and formulae into account [5][6][7][8]. A few SD bands are also known where the spins are experimentally determined [9][10][11][12][13][14][15][16].…”

The power index formula has been used to obtain the band head spin (I0) of all the superdeformed (SD) bands in Hg isotopes. A least squares fitting approach is used. The root mean square deviations between the determined and the observed transition energies are calculated by extracting the model parameters using the power index formula. Whenever definite spins are available, the determined and the observed transition energies are in accordance with each other. The computed values of dynamic moment of inertia J (2) obtained by using the power index formula and its deviation with the rotational frequency is also studied. Excellent agreement is shown between the calculated and the experimental results for J (2) versus the rotational frequency. Hence, the power index formula works very well for all the SD bands in Hg isotopes expect for 195 Hg(2, 3, 4).

“…Several approaches are proposed to calculate the spin proposition of SD bands [31,32]. The level spin for SD nuclei near the A∼ 194 mass region was introduced by Becker et al [33] in which transition energies of 25 SD bands of 13 nuclei were fitted by power-series expansion.…”

The systematics of kinematic moment of inertia J (1) and dynamic moment of inertia J (2) of superdeformed (SD) bands in A ∼ 130, 150, 190 mass regions have been studied. We have obtained the values of J (1) and J (2) for all the SD bands observed in the A ∼ 130, 150, 190 mass regions by using the experimental intraband E2 transition energies. The result of this work includes the variation of J (1) with the product of valence proton and neutron numbers (NpNn). The phenomenon of band mixing has been observed in the A∼130, 150 mass regions and band crossing has been observed in the A∼190 mass region. The systematics also includes the variation of J (2) with the product of valence proton and neutron numbers (NpNn). Evidence of staggering behaviour has been observed in all three A∼130, 150 and 190 mass regions. We present for the first time the variation of J (1) and J (2) of SD bands in the A∼130, 150, 190 mass regions with NpNn.
