Towards a new measurement of parity violation in ytterbium — •Dionysios Antypas1, Nathan Leefer1, Kostantin Tsigutkin2, and Dmitry Budker1,3 — 1Helmholtz Institut-Mainz, Mainz, Germany — 2ASML, Veldhoven, The Netherlands — 3Johannes Gutenberg Universitaet-Mainz, Mainz, Germany
The ytterbium (Yb) atomic parity violation (APV) experiment has succeeded in measuring the largest APV effect yet observed in any atom. Because of its size, and the availability of a chain of seven stable isotopes (including two with non-zero nuclear spin), studying APV in Yb is promising for measurements of the neutron distributions of the nucleus as well as for probing the nuclear anapole moment. The experiment recently moved from UC Berkeley to Mainz, and a new apparatus is currently under construction. We present the current state of the project, with emphasis on the next generation apparatus features that will allow us to perform sensitive measurements of the anapole moment and neutron skin contribution to the APV effect.
