“…In the case of Mo 108 nucleus (see figure 8), the staggering grows with increasing spin and it appears axially symmetric in nature at low spin, but at high spin it changes. This shows the triaxial behavior both in γ-band and γγ-band (also observed by Hui-Bo et al [15] for γ-band).…”

“…The spectroscopy of Ru 109 112 − was studied by measuring the prompt γ-rays produced by the f U( , ) 238 α fusion-fission reaction [12]. The high spin levels in Mo with gammasphere detector array [13][14][15]. The two-phonon vibrational states are present in these neutron-rich Mo nuclei.…”

“…The present approach of the work is to discuss the important aspects of an even-even Ru 112 nucleus and Mo isotopes such as excitation energies and odd-even staggering patterns both in one-phonon γ-band (K = 2) and two-phonon γγ-band (K = 4) by using the MSRF and experimental data, respectively. The calculations of the present work are also compared with the latest experimental information taken from [13][14][15]28], which includes a new band-like structure on band head of…”

The structure of multiphonon K = 4 γγ-band of Ru 112 , Mo 104 , Mo 106 , and Mo 108 nuclei are investigated using the recently proposed modified soft rotor formula (MSRF). The positive values of the moment of inertia and small values of softness parameter are obtained. The calculated values of moment of inertia of γγ-band are almost equal to the moment of inertia of γband, which indeed should be equal to the moment of inertia of ground band. The constant energy parameter EK in the MSRF is also illustrated for K = 4 γγ-band. The staggering pattern in the multiphonon γγ-band is also discussed in detail. The study of one-phonon K = 2 γ-band and two-phonon K = 4 γγ-band using MSRF yields good energy values.

“…Quantum phase transitions have been attributed as the driving force behind this rapid evolution of the nuclear shape [41,42]. Beyond N = 60, there is increasing evidence that the deformation softens towards the neutron drip-line and that the triaxial degree of freedom plays in an important role in the behaviour of neutron-rich molybdenum isotopes [43][44][45][46][47][48][49].…”

The ground-state properties of neutron-rich 106 Nb and its β decay into 106 Mo have been studied using the CARIBU radioactive-ion-beam facility at Argonne National Laboratory. Niobium-106 ions were extracted from a 252 Cf fission source and mass separated before being delivered as low-energy beams to the Canadian Penning Trap, as well as the X-Array and SATURN β-decay-spectroscopy station. The measured 106 Nb ground-state mass excess of -66202.0(13) keV is consistent with a recent measurement but has three times better precision; this work also rules out the existence of a second long-lived, β-decaying state in 106 Nb above 5 keV in excitation energy. The decay half-life of 106 Nb was measured to be 1.097(21) s, which is 8% longer than the adopted value. The level scheme of the decay progeny, 106 Mo, has been expanded up to ≈4 MeV. The distribution of decay strength and considerable population of excited states in 106 Mo of J ≥ 3 emphasises the need to revise the adopted J π = 1 − ground-state spin-parity assignment of 106 Nb; it is more likely to be J ≥ 3.
