Abstract

We analyze the transverse nuclear magnetizations of ¹²⁹Xe and ¹³¹Xe in a vapor cell containing natural Xe, ⁸⁷Rb, and buffer gases. The Xe atoms are polarized through spin-exchange optical pumping (SEOP) with Rb atoms under low-magnetic-field conditions. From the free-induction-decay (FID) signal, we measure the nuclear magnetization of the Xe atoms in the Xe-Rb vapor cell. Furthermore, we measure the dependence of the gyromagnetic ratio on the magnetization of ¹²⁹Xe and ¹³¹Xe by examining the amplitude of the FID signal of each isotope, and we evaluate the relationship between the magnetic field gradient and transverse relaxation rate for both of the ¹²⁹Xe and ¹³¹Xe isotopes.
