Double-beta decay will emit two neutrinos.
But, are they simultaneously released or separated?
But, are they simultaneously released or separated?
mfb said:Yes, they are emitted at the same time.
There are also many isotopes that will do a normal beta decay, where the produced nucleus will do another beta decay later, but that is not called double beta decay then.
That physical mechanism is the double beta decay.qnach said:To be emitted at the same time is really a magic unless there are some physical mechanism to make them
Are you sure?Orodruin said:The entire point with double beta decay is that the parent nucleus energetically cannot undergo single beta decay.
That is something of an anomaly where single beta decay is allowed but not very favourable energetically compared to the double beta decay. However, the double decay is a higher order process. Together these effects happen to give similar decay widths for the two types of decay but it is not the general situation for double beta decaying nuclei.snorkack said:Are you sure?
What is the decay energy and branching fraction of calcium 48 single beta decay to scandium 48?
Double-beta decay is a type of radioactive decay in which an atomic nucleus undergoes two beta decays, resulting in the emission of two electrons and two anti-neutrinos.
Neutrinos are emitted during the beta decay process, along with electrons. In double-beta decay, two beta decays occur simultaneously, resulting in the emission of two neutrinos.
The time between when the neutrinos are emitted in double-beta decay varies depending on the isotope undergoing decay. It can range from fractions of a second to hundreds of years.
The time between when the neutrinos are emitted can provide valuable information about the properties of neutrinos, such as their mass and flavor. It can also help in understanding the underlying mechanisms of double-beta decay.
The time between when the neutrinos are emitted is measured using specialized detectors that can detect the neutrinos and record the time of their emission. These detectors are typically placed near the source of the decay, such as a nuclear reactor or a radioactive sample.
