| Sumario: | Simple formulas for the 0+ → 0+ double beta decay matrix elements, as a function of the particle-particle strength g<SUP>pp</SUP>, have been designed within the quasiparticle random phase approximation. The 2<i>v</i> amplitude is a bilinear function of g<SUP>pp</SUP>, and all 0<i>v</i> moments behave as ratios of a linear function and the square root of another linear function of g<SUP>pp</SUP>. It is suggested that these results are of general validity and that any modifications of the nuclear Hamiltonian or the configuration space cannot lead to a different functional dependence. |
