I have a question that states: "Consider the shell model predictions for the ground state and low lying excited states of 210 Bi (see below for sidenote). This is just a definition issue really. I don't know what a 'low lying' state is. I can't find that term used in my text at all. Can someone explain that to me? *Sorry but I don't know how to write the superscript for the above isotope of Bismuth. Does anyone know how to do that?
