    "abstract": "We have extended the formalism for the two-neutrino double beta decay by\nincluding the weak-magnetism term, as well as other second-forbidden\ncorrections. The weak magnetism diminishes the calculated half-lives in $\\sim\n10%$, independently of the nuclear structure. Numerical computations were\nperformed within the pn-QRPA, for $^{76}Ge$, $^{82}Se$, $^{100} Mo$, $^{128}Te$\nand $^{130}Te$ nuclei. No one of the second-forbidden corrections modifies\nsignificantly the spectrum shapes. The total reduction in the calculated half\nlives varies from 6% up to 32%, and strongly depend on the nuclear interaction\nin the particle-particle $S=1,T=0$ channel. We conclude that the higher order\neffects in the weak Hamiltonian would hardly be observed in the two-neutrino\ndouble beta experiments.",
