摘要：

We report the results of an experimental investigation of the longitudinal relaxation time T-1 of the electronic polarization of the ground state of potassium atoms in cells with an antirelaxation coating on the walls. Investigations were performed for a number of cells at temperature T=24 degrees C. The maximum recorded relaxation times tau are 3.6, 4.3, and 5.2 s for cells with diameter D=50,75, and 100 nm, respectively. These are the longest longitudinal relaxation times ever recorded in coated cells. The transverse relaxation time was measured for these cells at the same temperature: T-2=0.72,1.1, and 1.4 s, respectively. (C) 1999 American Institute of Physics. [S0021-3640(99)00815-4].
