Well done. You've clicked the tower. This would actually achieve something if you had logged in first. Use the key for that. The name takes you home. This is where all the applicables sit. And you can't apply any changes to my site unless you are logged in.

Our policy is best summarized as "we don't care about _you_, we care about _them_", no emails, so no forgetting your password. You have no rights. It's like you don't even exist. If you publish material, I reserve the right to remove it, or use it myself.

Don't impersonate. Don't name someone involuntarily. You can lose everything if you cross the line, and no, I won't cancel your automatic payments first, so you'll have to do it the hard way. See how serious this sounds? That's how serious you're meant to take these.

Deformed nuclei possess enhanced moments violating time reversal invariance
($T$) and parity ($P$). Collective magnetic quadrupole moments (MQM) appear in
nuclei with a quadrupole deformation (which have ordinary $T$,$P$-conserving
collective electric quadrupole moments). Nuclei with an octupole deformation
have a collective electric octupole moment, electric dipole moment (EDM),
Schiff moment and MQM in the intrinsic frame which rotates with the nucleus. In
a state with definite angular momentum in the laboratory frame, these moments
are forbidden by $T$ and $P$ conservation, meaning their expectation values
vanish due to nuclear rotation. However, nuclei with an octupole deformation
have doublets of close opposite parity rotational states with the same spin,
which are mixed by $T$,$P$-violating nuclear forces. This mixing polarises the
orientation of the nuclear axis along the nuclear spin, and all moments
existing in the intrinsic frame appear in the laboratory frame (provided the
nuclear spin $I$ is sufficiently large to allow such a moment). Such a
mechanism produces enhanced $T$,$P$-violating nuclear moments. This enhancement
also takes place in nuclei with a soft octupole vibration mode. In this paper
we present updated estimates for the enhanced Schiff moment in isotopes of Eu,
Sm, Gd, Dy, Er, Fr, Rn, Ac, Ra, Th, Pa, U, Np and Pu in terms of the
CP-violating $\pi$-meson--nucleon interaction constants
$\bar{g}_{0},\bar{g}_{1}$ and $\bar{g}_{2}$, the QCD parameter $\bar{\theta}$
and the quark chromo-EDMs. The implications of the enhanced $T$,$P$-violating
moments to the search for axion dark matter in solid state experiments are also
discussed, with potential alternative candidate compounds in which we may
expect enhanced effects suggested.
