Calculate the Coulomb barrier height for two 7Li nuclei that are fired at each other with the same initial kinetic energy K.

2H is a loosely bound isotope of hydrogen. Calleddeuterium or heavy hydrogen, it is stable but relativelyrare—it is 0.015% of natural hydrogen. Note that deuteriumhas Z = N , which should tend to make it more tightlybound, but both are odd numbers. Calculate BE/A , thebinding energy per nucleon, for 2H and compare it with theapproximate value obtained from the graph in Figure.

Q.7 (b) The a-particle of energy 14 MeV incident on a Ni60 nucleus and form the compound nucleus Zn64 via the following reactions: He + Ni60 → Zn64 Calculate the excitation energy of Z64 relative to the ground state Zn64. (Given: M (Ni) = 59.930878u, M(Zn64) = 63.92914u and M(He) = 4.00260 amu.

Technetium has not been found in nature. It can be obtained readily as a product of uranium fission in nuclear power plants, however, and is now produced in quantities of many kilograms per year. One medical use relies on the tendency of 99mTc (an excited nuclear state of 99Tc) to concentrate in abnormal heart tissue. Calculate the total activity (in disintegrations per second) caused by the decay of 1.0 mg of 99mTc, which has a half-life of 6.0 hours.
