We present a detailed description of the observation of parity violation in the 6s 2 1 S0 ! 5d6s 3 D1 408-nm forbidden transition of ytterbium, a brief report of which appeared earlier. Linearly polarized 408-nm light interacts with Yb atoms in crossed E- and B-fields. The probability of the 408nm transition contains a parity violating term, proportional to (E · B)[(E × E) · B], arising from interference between the parity violating amplitude and the Stark amplitude due to the E-field (E is the…

Isotopic variation of parity violation in atomic ytterbium

The weak force is the only fundamental interaction known to violate the symmetry with respect to spatial inversion (parity). This parity violation can be used to isolate the effects of the weak

Parity violation experiment in Yb is made on the strongly forbidden M1 transition 6s^2 1S0 \to 5d6s 3D1. The hyperfine mixing of the 5d6s 3D1 and 5d6s 3D2 levels opens E2 channel, whose amplitude

Measuring nuclear-spin-dependent parity violation with molecules: Experimental methods and analysis of systematic errors

Nuclear spin-dependent parity violation (NSD-PV) effects in atoms and molecules arise from $Z^0$ boson exchange between electrons and the nucleus, and from the magnetic interaction between electrons

Parity and Time-Reversal Violation in Atomic Systems

Studying the violation of parity and time-reversal invariance in atomic systems has proven to be a very effective means of testing the electroweak theory at low energy and searching for physics

Atomic parity violation in 0-to-0 two-photon transitions

We present a method for measuring the nuclear anapole in a string of francium isotopes. The anapole is a parity non-conserving electromagnetic moment that enables parity-forbidden transitions between



Observation of a large atomic parity violation effect in ytterbium.
