Fusion processes, like combining two deuterons to form a \(\mathrm{He}\)-nucleus are impossible at ordinary temperatures and pressure. The reasons for this can be traced to the fact:
| (a) | nuclear forces have short-range |
| (b) | nuclei are positively charged |
| (c) | the original nuclei must be completely ionized before fusion can take place |
| (d) | the original nuclei must first break up before combining with each other |
