The dissociation of a 199Hg2 dimer prepares an entangled state of two spatially separated
199Hg atoms, each with nuclear spin 1/2, and with zero total electron and nuclear spin
angular momenta. This is identical to the entangled state of the two spin 1/2 particles in
Bohm’s classic version of the EPR gedankenexperiment. An analysis of the rotational
structure of the CD=57HCI=0 band of the D3K+
u (1u)HX1Kg
+ (0+
g ) transition in Hg2 (natural
abundance) is presented. The analysis of the fluorescence excitation spectrum using a dye
laser gives the values of the constants BCD=57 and BCI=0 for the excited and ground electronic
energy states involved in the transition, respectively. To increase the accuracy of the
rotational constants and resolve the fine spectrum of the Hg2, a continuously tunable single
longitudinal mode laser with ultra-narrow line-width is needed. Measurements using a
narrow line-width alexandrite laser had been attempted and the values of BCD=57 and BCI=0
were determined. To improve the quality of the laser beam and hence the precision of the
rotational constants, modifications have been made to the cavity of the alexandrite laser.
This provides a possibility for further investigation.
