    "abstract": "After briefly reviewing $\\beta \\beta$ decay as a test of the neutrino mass, I\nexamine the nuclear structure involved in this process. Simple formulas (\\`{a}\nla Pad\\\u0027{e}) are designed for the transition amplitudes and the general\nbehavior of $\\beta \\beta$ decay amplitudes in the quasiparticle random phase\napproximation are discussed. Results of a calculation for $^{48}Ca$, $^{76}Ge\n$, $^{82}Se$, $^{100}Mo$, $^{128}Te$ and $^{130}Te$ nuclei are presented, in\nwhich the particle-particle interaction strengths have been fixed by invoking\nthe partial restoration of the isospin and Wigner SU(4) symmetries. An upper\nlimit of $ \u003cm_{\\nu}\u003e\\approx 1$ eV is obtained for the effective neutrino mass.",
