Core reactions that occur:
¹⁴₇N + ⁴₂He → ¹⁷₈O + ¹₁H
Can be written :
¹⁴₇N (α, H) ¹⁷₈O , α = ⁴₂He
<h3>Further explanation </h3>Fusion and fission reactions are reactions involving atomic nucleus reactions
Fission reaction is a nucleation division reaction by firing a particle usually neutron so that it gets smaller particles of atomic nuclei.
A fusion reaction is a combining reaction of 2 atomic nuclei. Usually what is often used is a reaction between the hydrogen isotope that will form Helium
At the core, the reaction applies the law of eternity
- 1. energy
the energy before and after the reaction is the same
- 2. atomic number
the number of atomic numbers before and after the same
- 3. mass number
the number of mass numbers before and after the same
Particles that play a role in core reactions include
- alpha α particles ₂He⁴
- beta β ₋₁e⁰ particles
- gamma particles γ
- positron particles ₁e⁰
In general, the core reaction equation can be written:
<h3> X + a ---> Y + b + Q </h3>
X = target core
a = particle fired
Y = new core
b = the particle produced
Q = heat energy
or can be written simply
<h3> X (a, b) Y </h3>
In the ¹⁴₇N atomic nucleus, a fusion reaction occurs with ⁴₂He which produces isotopes of Oxygen and ¹₁H protons.
¹⁴₇N + ⁴₂He → ¹⁷₈O + ¹₁H
This reaction can be written down
¹⁴₇N (α, H) ¹⁷₈O
