    "abstract": "The structure of the collective low-energy $J^{\\pi}=0^{-}$ (T=0 and T=1)\nmodes is studied for a doubly magic nucleus in a schematic analytic model of\nRPA. The $0^{-}$ phonon states ($T= 0,1$) lie at energies $E_{T=0}(0^{-}) \\alt\n\\omega$ and $E_{T=1}(0^{-}) \u003e \\omega$, where $\\omega$ is the oscillator\nfrequency. The matrix elements of P-odd and P- and T-odd weak one-body\npotentials connecting the ground state to these $0^{-}$-states, $W_{coll}$, are\nenhanced by the factor $\\sim 2 (\\frac{\\omega}{E})^{1/2}A^{1/3} \\sim 10$ as\ncompared to the single-particle value $w_{sp}$ what can result in values\n$|W_{coll}| \\sim 20-30 eV$ if standard values of DDH parameters are used for\n$w_{sp}$. Similar enhancement arises in the P- and T-odd case.",
