Factor of 3

Thanks again, this is the usual factor 3 of the electric dipole field. It should appear in Eqs. (17), (23) and (31). The calculation of Eq. (38) should be repeated by computer using this factor 3 and I will repost the final result. The final result should of course be the one to be posted and translated.

Subj: Re: Typo corrected

In eq. 7 of UFt 393 there is a factor of 3 in front of the term r(p*r). This factor seems to be missing in eqs. 17 ff. Could you please verify this? Then we have to add this factor in the calculations with delta r.

OK thanks again, I will use this version for the reposted paper. It looks to be the same as the previous version.

There was a typo in the formula for the electric field, has been corrected.
