Q4: Using the principle of precision, prove the impossibility of an electron inside the nucleus, noting that the core's radius is 1×10-1ªm

A D-T pellet is heated by intense laser beams with wavelength of 2 μm. (1) Find the D-T plasma density at which the parametric decay instability (PDI) can occur. (2) Explain how the PDI-generated hot electrons can change ion damping.

Q2. An aluminum absorber of thickness 8 g/cm. The beam intensity is 8.24 J/ m s. a) Calculate the fraction of photons transmitted without interaction. b) What is the total transmitted beam intensity? c) What is the rate of energy absorption per unit mass in the aluminum?

Sketch the potential for a-decay, assuming it can be modelled as a pre-formed particle inside the daughter nucleus. On this sketch, illustrate a typical tunnelling wave-function, which has an energy Q which is less than the potential for R R.) 2
