I would like to make a few comments about double beta decay page: 1) I do not completely agree that double beta decay was discovered in 1986; it has been seen before in geochemical experiments. In 1986, M. Moe discovered two-neutrino mode of 82Se in direct measurement with TPC at UC Irvine. 2) 48Ca, 96Zr can also decay via a single beta decay and it has been seen recently. 3) For more details, please visit http://www.nndc.bnl.gov/bbdecay.

Thank you, but I don't know about observation of single beta for 48Ca and 96Zr, could you please provide the references? --V1adis1av 21:47, 22 September 2007 (UTC)

[edit] About the neutrinoless double beta decay

I don't agree when you say that an neutrino is an Majorana particle, indeed, in 1955 Davis used and reaction with an neutrino and 37Cl wich produces and electron an 37Ar, this is a clasical proof that the neutrinos are Dirac particles. I saw a reference in Wong pp. 202-203. —Preceding unsigned comment added by 201.141.39.114 (talk) 22:49, 6 October 2007 (UTC)
