# Equation for neutron proton-fusion, and deuterium photodiss.

• Flucky
In summary, the equations for neutron and proton fusion to form deuterium are p + p -> D and p + n -> D, respectively. And the equation for deuterium photodissociation is D + γ -> p + n. However, the latter is forbidden by energy conservation and some energy must be dissipated, mainly through photon emission.

## Homework Statement

Write the equations for neutron and proton fusion to form deuterium and for deuterium photodissociation.

## The Attempt at a Solution

There is plenty on proton-proton fusion to form deuterium, but not much on proton-neutron.

Is it simply p + n -> D ?

Is deuterium photodissociation D + γ -> p + n ?

Flucky said:

Yes.

p + n -> D is forbidden by energy conservation. Some energy has to get dissipated, mainly as photon emission.

Forgot I had posted this question. Thanks!

## 1. What is the equation for neutron proton-fusion?

The equation for neutron proton-fusion is n + p → D + γ, where n represents a neutron, p represents a proton, D represents a deuterium nucleus, and γ represents a gamma ray photon.

## 2. How is deuterium photodissociation represented in an equation?

The equation for deuterium photodissociation is D + γ → n + p, where D represents a deuterium nucleus, γ represents a gamma ray photon, n represents a neutron, and p represents a proton. This is the reverse reaction of neutron proton-fusion.

## 3. What is the purpose of the equation for neutron proton-fusion?

The equation for neutron proton-fusion represents the process by which two nuclei, a neutron and a proton, combine to form a larger nucleus, deuterium. This reaction is an important part of nuclear fusion, which is the process that powers stars and can potentially be harnessed as a source of energy on Earth.

## 4. How does the equation for deuterium photodissociation relate to nuclear reactions?

The equation for deuterium photodissociation represents a type of nuclear reaction, specifically a photodissociation reaction. In this reaction, the energy from a gamma ray photon is used to split a deuterium nucleus into its constituent parts, a neutron and a proton. This reaction is important in understanding how stars produce energy and in the development of nuclear fusion technology.

## 5. Are there any practical applications of the equation for neutron proton-fusion and deuterium photodissociation?

The equation for neutron proton-fusion and deuterium photodissociation have several practical applications. The most well-known is in nuclear fusion research, where scientists are working to develop a sustainable energy source based on these reactions. These equations also play a role in understanding the production of elements in stars and in nuclear weapons technology.
