\item \textbf{\textit{Hur sammansätts kärnspinnet I?}}  Man adderar spinnen för varje nukleon helt enkelt.  \item \textbf{\textit{Vad menas med en kärnas partitet $\pi$?}}  Kärnans paritet kan antingen vara + (jämn) eller - (udda). "Parity involves a transformation that changes the algebraic sign of the coordinate system. Parity is an important idea in quantum mechanics because the wavefunctions which represent particles can behave in different ways upon transformation of the coordinate system which describes them." http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/parity.html \url{http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/parity.html}  \end{enumerate}
