1 Free jazz almost by definition is free of such structures, but also by definition (it is, after all, jazz as much as it is free) it retains much of the language of earlier jazz playing. 2  It is therefore very common to hear diatonic, altered dominant and blues phrases in this music.
The main overall nuclear fusion reaction is the fusion of four hydrogen atom nuclei to form a bigger nucleus of a helium atom i.e. 4 1H1 $\rightarrow$ 4He2 + 2 0e+1+ energyi.e., 4 Hydrogen nuclei -----> Helium nucleus + 2 positrons + energy.
nuclear fission involves the splitting of a heavy nucleus into lighter nuclei while nuclear fusion involves the combining of light nuclei into a single heavier nucleus both processes produce vast amounts of energy but each has its own unique set of advantages and disadvantages as an energy source
