Hi all, I wanted to know what a physicist should do when they simply don't feel their A-game. I need to solve the Schrodinger equation in reduced-mass coordinates for a finite spherical well in order to model a deuteron in preparation for a talk on Friday, and I simply can't think straight. My back hurts, I'm sleepy, and...gah. I mean, I'm ready to suck it up and truck on, but that just affects my creativity. Not sure what to do. There is a solution all worked out somewhere, but I don't want to look at it until I've come up with a solution of my own. Suggestions? I think I know what the answer is already, but I need to hear it from outside of me.
