Due to an unfortunate error, equation (16) is wrong. The correct analytic expression of the rate coefficient given in Fig. 4 is:
The suggestion given in the concluding remarks that the upper limit of the hydrogen density is a fraction of is no longer correct. To prevent complete collisional depolarization of the ground state of Na, the maximum value of is a fraction of .
