Geigar Nutall Law
« on: November 11, 2006, 04:02:11 AM »
This question refers to #3 in Chapter 7 of Loveland:

In the Geiger Nutall Law:

log(t1/2) = A + B/(SQRT Qalpha) where SQRT means square root, how does one determine the constants A and B for 282Gd and 262Sg?

Use Eqn 7.7 if you can't find A and B. Just remember to cite everything.

Can we use the hatsukawa, Nakahara, and Hoffman equation from page 185 of Loveland? It isn't perfect, but any Gamow factor calculation would seem to take very long

I would like to know if it works anyways.
