“…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.…”

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 .

The recently proposed Fully-Renormalized QRPA (FR-QRPA), which fullfils the Ikeda sum rule (ISR) exactly, is applied to the two-neutrino double beta decay of 76 Ge, 82 Se, 100 Mo, 116 Cd, 128 Te and 130 Xe. The results obtained are compared with those of other approaches, standard QRPA and self-consistent QRPA (SCQRPA). The similarities and the differences among the methods are discussed. The influence of the restoration of the Ikeda sum rule on the 2νββ-decay amplitude is analyzed.21.60.Jz, 23.40.Hc

“…The reason why this interest has been increasing intensely is the consideration of the effective interaction in the particleparticle (pp) channel [1][2][3][4][5][6][7][8][9][10][11][12][13]. This effective interaction was included to get a better agreement between the calculated values of 2νββ decay nuclear matrix elements using quasiparticle random phase approximation (QRPA) method and the corresponding experimental data.…”

“…However, the inclusion of the pp effective interaction leads to two different problems: the first problem is the sensitivity of nuclear matrix element (NME) to the pp effective interaction constant and the second is that NME suddenly goes to zero at a certain value of the constant. There are some attempts [8][9][10][11][12][13] to overcome the above-mentioned difficulties. These attempts are usually related to the use of higher versions of QRPA method, but the calculation results show that the use of the higher versions of QRPA is not successful enough in overcoming these difficulties.…”

The investigation of the 2νββ decay by Pyatov method within quasiparticle random phase approximation formalism

The violated commutation condition between the total shell model Hamiltonian and Gamow-Teller operator (GT) has been restored by Pyatov method (PM). The considered nuclear model Hamiltonian in PM includes the separable GT residual interaction in ph and pp channels and is differentiated from the traditional schematic model by h0(restoration term). The influence of the h0 effective interaction on the 2νββ decay of 48 Ca, 76 Ge, 82 Se, 96 Zr, 100 Mo, 116 Cd, 128,130 Te and 136 Xe is investigated. All the calculations have been done within the framework of standard QRPA. The results obtained by PM are compared with those of other approaches and experimental data. The influence of the restoration term on the stability of the 2νββ decay nuclear matrix elements is analysed.
