### What is it that make nuclear fusion so difficult at low temperatures? There is plasma existing at low temperatures, so what does it make for fusion to be so difficult to reach at ambient temperatures?

### I got confused when I was researching about “neutron’s discovery in Chadwick’s experiment”. There was a nuclear equation said that when we bombard the alpha particles into beryllium, it will emits neutron particles as shown in this equation${}^{9}\mathrm{B}\mathrm{e}+\alpha {\left(}^{4}\mathrm{H}\mathrm{e}\right)\to {}^{12}\mathrm{C}+{}^{1}\mathrm{n}$What I am confused about is, isn’t the equation above a nuclear fusion reaction? As far as I know, nuclear fusion reactions require really high energy like on the Sun, but this experiment happens in a laboratory. So I wonder if nuclear fusion reactions can happen in laboratory, why can’t we use it to produce clean energy?

### How do molecules having speeds many times greater than mean speed help in making nuclear fusion reactions in a laboratory?

### Is the fact that Iron is attracted to magnets in any way related to the fact that it is also the element occupying the singular periodic table position where the chains of nuclear fission and fusion converge?Or is this just a coincidence?

### Why don't the nuclear fusion processes inside the sun produce ${\overline{\nu }}_{e}$ despite having the same mass as ${\nu }_{e}$? Is the reason as simple as "there is no production channel for ${\overline{\nu }}_{e}$s." ?

### Science project on the Sun. I have found that in order for nuclear fusion to work, it needs both helium 3 and 4.1. Why can't nuclear fusion be done with just helium 4?2. How can we create nuclear fusion on Earth?3. Can we even do so?

### Apart from thermo-nuclear reactions in the Sun, (and in hydrogen bombs and other methods developed by scientists) does nuclear fusion occur naturally in the planets? If not, why?Also, do the Sun and the Outer planets - Jupiter through Neptune - have rocky cores similar to the Earth (consisting of iron, nickel, silicon etc) in addition to the gases? I have read that there is not much of hydrogen or helium in the inner planets because of their low escape velocities and the solar winds from the Sun. Hence only the heavier elements remained.

### Birth of a star. Now in order for a star (or proto-star) to be born, there must be nuclear fusion that happens between hydrogen atoms. My question is what happens to the electrons? Sal never mentions them, only isotopes of hydrogen, and basically only focuses on the nucleus of the atom. Do the electrons even matter?

### At the temperature range of ordinary fire or maybe even ordinary boiling water, is the Coulomb potential between light atomic nuclei occasionally overcome to give way to fusion?Basically, how are the nuclear fusion cross sections calculated and are they a function of temperature?

### Once the commercial nuclear power plant is built for electricity production , after this what kind of research does scientists do in nuclear fusion power. Why I am asking this question is ITER is planning to build the fusion reactor in 2030s , So after what research does nuclear fusion scientists do?

### Given the extremely high plasma temperatures that are required to sustain a nuclear fusion reaction in a device such as a tokamak reactor, how can such high temperatures be maintained in the presence of radiative heat transfer from the plasma to the walls of the reactor vessel?

### Is it possible to use nuclear fusion and fission to create new elements? For example, if you have a carbon dioxide molecule, break the bond between carbon and oxygen, and use nuclear fusion/fission to make a new element, or use those electrons, protons, and neutrons to make an element, bond it with another element, and maybe the new molecule be more useful than carbon dioxide. Not sure If I'm missing something here, because nuclear fission and fusion would solve the whole world's problems if it were really this easy. So there's probably a monetary cost, or a high-risk, or something else I'm missing.

### Theoretically, if we just create a high pressure with low (room 20C) temperature, at some point nuclear fusion can be started.Is there any research on this topic, how high should be this pressure for different type of reaction? Maybe someone has some numbers in mind, how many GPa should we have to achieve it?

### Confined plasma in electromagnetic field uses in TOKAMAK nuclear fusion reaction. But I don't know what is the main role of plasma in fusion reaction. Is it use for producing energy required to fuse nuclei or something else?

### The energy released in a nuclear fusion reaction, consider:I was wondering from where the heat and light energy is coming in sun through these reactions, if whole of the energy released is carried as the kinetic energy of the products?

### In nuclear fusion, the colliding particle unites with the parent and fuses into a single nucleus with a higher mass. Sometimes other small particles (n, p) are given off.However, that is not the case for the reaction:${}_{14}^{7}\text{N}{+}_{1}^{0}\text{n}{\to }_{14}^{6}\text{C}+{}_{1}^{1}\text{H}$If so, why would you still consider it as a nuclear fusion? I have come up with a theory that it is because the carbon has an extra neutron than Nitrogen. Is this correct?

### When the spacecraft's fusion efficiency is 0.01%, the spacecraft's fusion fuel is 1t, and the total mass of the spacecraft is 1.2t, the friend bet the final speed of the spacecraft is 80% of the speed of light. The state of the fuel at nuclear fusion is assumed to be D + T and 0.01% of the maximum energy of the fusion of the fuel, although the fusion method has not yet been firmly determined. I am curious about the answer of the final speed of this space ship.

### This might sound silly. But we always talk about nuclear fusion in stars and I have always wondered why this process happens at all.Is it inevitable for fusion to happen at the temperature and pressure present in a star?

### Suppose there exists an alpha particle in the nucleus. Within a radius of 2 femtometer, the dominating force is the nuclear force but beyond this radius, the Coulomb force becomes the effective dominating force due to it's longer range force. Outside this radius is a daughter nucleus.So let's suppose the alpha particle moves beyond the effective range of the nuclear force,the electric potential energy due to the force between the alpha particle and the daughter nucleus is given by as${U}_{B}=\frac{1}{4\pi {\epsilon }_{0}}\left(\frac{2\left(Z-2\right){e}^{2}}{R}\right).$Why is there the term
