Other decay modes are possible if the excitation energy is greater, fewer are possible if this energy is less. In addition, 1N* can simply lose its excitation energy by emitting one or more gamma rays.

  7. Nuclear Cross Section To characterize the probability that a certain nuclear reaction will take place, it is customary to define an effective size of the nucleus for that reaction, called a cross section. The cross section is defined bv cross section Inumber of incident particles per unit time per unit area. Rnumber of reactions per unit time per nucleus The cross section has the units of area and is on the order of the square of the nuclear radius. A commonly used unit is the barn: 1 barn = 10-28 m2
