Hello ChoppyDunbar and Welcome to Wikipedia! Welcome to Wikipedia! I hope you enjoy the encyclopedia and want to stay. As a first step, you may wish to read the Introduction. If you have not already created a account here, note that you do not have to log in to read or edit articles on Wikipedia, but creating an account is quick, free and non-intrusive, requires no personal information, and there are many benefits of having a username. Without a username, your IP address is used to identify you. If you have any questions, feel free to ask me at my talk page — I'm happy to help. Or, you can ask your question at the New contributors' help page. Here are some more resources to help you as you explore and contribute to the world's largest encyclopedia...

If you would like to play around with your new Wiki skills the Sandbox is for you. Bduke (Discussion) 08:39, 19 February 2011 (UTC)

I have copied you question about Absorption cross section to Talk:Absorption cross section for comment there. I think there may be several ways of getting this correct, and I want to know how the people working in the area handle it. It is not something I know a lot about. --Bduke (Discussion) 08:39, 19 February 2011 (UTC)
