“…This seems to be a characteristic problem with the transitions to excited states in 100 Ru since similar difficulties were faced in the earlier calculations of Ref. [78,79]. In these studies a simultaneous prediction of the two-neutrino double-β-decay rate of 100 Mo and the β-decay rates of 100 Tc was attempted and the g pp parameter of the pnQRPA was used for this purpose.…”

The β decay of 100 Tc has been studied by using the total absorption γ -ray spectroscopy technique at the Ion Guide Isotope Separator On-Line facility in Jyväskylä. In this work the new Decay Total Absorption γ -ray Spectrometer in coincidence with a cylindrical plastic β detector has been employed. The β intensity to the ground state obtained from the analysis is in good agreement with previous high-resolution measurements. However, differences in the feeding to the first-excited state as well as weak feeding to a new level at high excitation energy have been deduced from this experiment. Theoretical calculations performed in the quasiparticle random-phase approximation framework are also reported. Comparison of these calculations with our measurement serves as a benchmark for calculations of the double β decay of 100 Mo.

“…Moreover, it has been already conjectured that the deformation can play a crucial role in case of ββ decay of 100 Mo and 150 Nd [29,30]. Further, all the nuclei undergoing ββ decay are even-even type, in which the pairing degrees of freedom play an important role.…”

“…The predicted T 2ν 1/2 in QRPA by Staudt et al [45] and in OEM by Hirsch et al [46] are larger than our predicted value for g A =1.0 by approximately a factor of 2 and 4 respectively. The 2ν ββ decay of 100 Mo for 0 + →0 + transition have been investigated by many experimental groups [18,51,[57][58][59][60][61][62][63][64][65] as well as theoreticians by employing different theoretical frameworks [29,30,[45][46][47]52,53,56,[66][67][68]. In comparison to the experimental M 2ν , the theoretically calculated value given by Stoica using SRPA(WS) [53] is too small.…”

Two-neutrino double- β decay of 94 ⩽ A ⩽ 110 nuclei for the 0+ → 0+ transition

The two neutrino double beta decay of 94,96 Zr, 98,100 Mo, 104 Ru and 110 Pd nuclei for 0 + → 0 + transition is studied in the PHFB model in conjunction with the summation method. In the first step, the reliability of the intrinsic wave functions has been established by obtaining an overall agreement between a number of theoretically calculated spectroscopic properties and the available experimental data for 94,96 Zr, 94,96,98,100 Mo, 98,100,104 Ru, 104,110 Pd and 110 Cd isotopes. Subsequently, the PHFB wave functions of the above mentioned nuclei are employed to calculate the nuclear transition matrix elements M 2ν as well as half-lives T 2ν 1/2 . Further, we have studied the effects of deformation on the M 2ν .

“…In this case there are only 3 candidate events in the 2.8-3.2 MeV window with 2.8 (2.0+0.8) expected. With an efficiency of 4.2% this gives T 1/2 > 1.8 · 10 23 y (90% CL) and < λ > < (1.5 − 2.0) · 10 −6 , using the NME from [28].…”
