Using parity-nonconserving spin-spin coupling to measure the Tl nuclear anapole moment in a TlF molecular beam

NUCLEAR MOMENTS Tl; analyzed available data; deduced new experiment in search of for a Time Reversal-invariance conserving but Parity-nonconserving (PNC) effect induced by the anapole moment of the Tl nucleus, via a vector coupling of the two nuclear spins in TlF.
