The online version of this article has been updated. In the Abstract, lines 6–7 now reference Burnett and Kroll in Phys. Rev. Lett. 20:86–88, 1968 instead of Bell and Van Royen. Additionally, in line 9, the reference to Bell and Van Royen (1969) has been replaced with Burnett and Kroll (1968).

The original article has been corrected.
