Posted February 08, 2019 14:18:54With a diameter of 1.3 microns and a mass of 2.5 electron volts, Fe ions can be a little tricky to detect.
But new research by scientists at the University of California, Berkeley, has found that the Fe ions have a much lower energy density than previously thought, which could be useful for detecting these electrons.
The researchers found that, even though the Fe ion spins are extremely low-energy, their magnetic properties are not as bad as previously thought.
This means they can be used to detect electrons, even in the absence of an external magnetic field.
“These Fe ions are the ones that we see in nature.
So the electron spin is like a little puzzle piece,” said senior author Dr Ravi Kumar.”
If you want to detect the electrons, you have to know what their charge is and how many electrons they have.
And if you want them to do something, you need to know the charge and the energy density of that spin.”
The research was published in Nature Communications.
The new finding will be of great interest to physicists, who have long wondered about why Fe ions spin so fast.
“We thought that because Fe ions don’t have much energy, they would not be capable of interacting with the electron spins,” said lead author Dr James Menezes, a physicist at UC Berkeley.
“But if you take a closer look at the Fe atoms, you will see that they actually have a lot of energy and a lot more charge than previously expected.”
So we are able to determine that they have a very low energy and the high energy density.
“The researchers also found that electrons are not made from the same atoms as they are from other Fe ions.”
For example, a Fe atom has two different types of atoms.
In one case it has a neutral, negatively charged Fe atom, and in the other it has an electron that has an positive charge,” Dr Kumar said.”
When electrons are being created, the neutral Fe atom gets knocked off the neutral state and spins into the negatively charged electron.
“These spin variations are caused by a process called electron spin recombination, in which two different Fe atoms form pairs that can be recombined into one another.”
In this case, two pairs of Fe atoms are spinning in opposite directions, and that spins produces a new pair of Fe electrons,” Dr Menezers said.
It’s this process that is used by Fe ions to interact with electrons.
Electron spins in the Fe atom are formed by the collision of two different atoms.
The electrons in the atoms are not just attracted to each other, but they also attract each other to each another.
This is the way Fe ions interact with each other.”
The two electrons in a Fe atoms pair are actually like a magnet in the magnetron, like a pair of magnets, and the spin of that magnetron creates the spin variations in the electron orbits,” Dr Gupta said.
Electrons can also interact with other particles in the Earth’s atmosphere.
They can even form an ion that travels in front of an electron, which is similar to what happens when an electron interacts with a gas such as helium or nitrogen.
Dr Kumar and his team hope to one day use Fe ions as the “mechanical glue” for building a new kind of particle detector.”
The key is to have a spin that gives the particle an attractive charge, so it can be picked up and tracked by an external detector,” Dr Ajay Gupta said, adding that they are still in the early stages of their research.”
The way we want to do this is to build a new detector for this particle and find the spin variation that gives us the electron-phonon interaction.”
