Talk:Kaufmann–Bucherer–Neumann experiments

Comments

I've written and expanded the articles on Alfred Bucherer and Walter Kaufmann (physicist). Those edits are based on the descriptions of Miller and Janssen. I think it's time to expand this main article as well. --D.H (talk) 16:43, 29 August 2008 (UTC)

You might note in both discussions that the increase in mass as an explantion of the unexpected decrease in the rate of increase of deflection could as easily be attributed to a change in the magnetic interaction, eg spin or charge polarization inside the beta electrons, with the mass unchanged. What do you think? Aesop111 (talk) 21:30, 20 May 2009 (UTC)

Some extra references that might be interesting to chase up

Updated

Now, I have expanded this article (originally written by User:Awolf002) and moved it, including the full version history, into the main Name-space. --D.H (talk) 17:44, 25 April 2011 (UTC)
