## Measurement of the forbidden electric tensor polarizability of Cs atoms trapped in solid ⁴He

### In: Physical Review A, 2007, p. 042505

We have measured the electric tensor polarizabilities of the hyperfine levels of Cs atoms embedded in a body-centered cubic ⁴He crystal. The polarizabilities are inferred from the shift of optically detected magnetic resonance lines in each hyperfine level induced by static electric fields up to 50 kV/cm. We recorded the magnetic resonances both by scanning the rf frequency and in a... More
