For $\theta=0$ or $\theta=\pi$ the cosine is $\pm 1$. The case $\theta=0$ is called parallel (signed with p) and $\theta=\pi$ (signed with a) is called antiparallel. Mulitpling these two cases you obtain

At the storage ring TSR in Heidelberg laser spectroscopy with ions at 3 percent and 6.4 percent were carried out. As transition a closed two level system of the metastable triplet and saturation spectroscopy was used. The transition wavelength is 548 nm. At 3% the parallel laser was a solid state laser at 532 nm and as parallel laser a dye laser at 565 nm was used. The laser for 6.4% were a dye laser at 585 nm and an argon ion laser 514 nm.

For theta=0 or theta=pi the cosine is +/-1. The case theta=0 is called parallel (signed with p) and theta=pi (signed with a) is called antiparallel. Mulitpling these two cases you obtain

nu_0=nu_p*gamma(1-beta) nu_0=nu_a*gamma(1+beta) =>nu_0^2=nu_p*nu_a*gamma^2(1-beta^2)

If gamma=gamma_SR is reduces to

nu_0^2=nu_p*nu_a.

$$\gamma_{SR}=1/\sqrt{1-\beta^2}.$$

For $\theta=0$ or $\theta=\pi$ the cosine is $\pm 1$. The case $\theta=0$ is called parallel (signed with p) and $\theta=\pi$ (signed with a) is called antiparallel. Mulitpling these two cases you obtain

$$\nu_0=\nu_p*\gamma(1-\beta)$$ $$\nu_0=\nu_a*\gamma(1+\beta)$$ $$\Rightarrow \nu_0^2=\nu_p*\nu_a*\gamma^2(1-\beta^2)$$

Determination of alpha and alpha2 parameters from Robertson-Mansouir-Sexl (RMS) test theory

In RMS several test parameters are introduced by expanding a function in velocity. For the experiment the relation between the test parameters and the measured values are:

"measured values"

  • nua=frequency light antiparallel to ion movement
  • nup=frequency light parallel to ion movement
  • nu1=rest frequency transition 1 of lambda system
  • nu2=rest frequency transition 2 of lambda system
  • beta=velocity of ions

  • alpha=(epsilon-1)/(2*beta^2)
  • alpha2=1/2*((epsilon-1-2*alphal*beta^2)/beta^4-alphal)
