Is nuclear decay reversible?

Yes, radioactive decay is reversible in time. If you imagine filming the decay process, and then running the movie backwards, what you would see is a perfectly allowed process: the decay products come together and form the original nucleus.

What happens to particles that decay?

Particle decay is the spontaneous process of one unstable subatomic particle transforming into multiple other particles. The particles created in this process (the final state) must each be less massive than the original, although the total invariant mass of the system must be conserved.

Is beta decay reversible?

According to physics as we know it today, the short answer is no, radioactive decay is not reversible. Radioactive decay comes in a variety of mechanisms (alpha decay, beta decay, electron capture, etc.) and once the energy released as part of this decay occurs, it is not something you can then reverse.

Can an atom be reversed?

NO! One single case in which the reversal cannot be done, and the unitarity was disproved.

Can we speed up radioactive decay?

The rate of this kind of decay depends on the chance of an electron straying into the nucleus and getting absorbed. So increasing the density of electrons surrounding the atomic nucleus can speed up the decay.

How long does it take for particles to decay?

It turns out that left alone, a free neutron (one that isn’t bound in a nucleus) will spontaneously decay into a proton, and electron and a neutrino (this is called “beta decay”). The characteristic time for the decay to occur is about 15 minutes.

Can you send a particle back in time?

Hypothetical superluminal particles called tachyons have a spacelike trajectory, and thus can appear to move backward in time, according to an observer in a conventional reference frame.

Can time have particles?

Time comes from every particle within our bodies, including our DNA that is made of these same atoms and particles. Time is the frequency of longitudinal energy waves. However, time is not constant. The evidence for time’s relation to wave frequency is based on Einstein’s relativity.

What is the difference between particle decay and radioactive decay?

Particle decay. The term is typically distinct from radioactive decay, in which an unstable atomic nucleus is transformed into a lighter nucleus accompanied by the emission of particles or radiation, although the two are conceptually similar and are often described using the same terminology.

What is an unstable particle?

Unstable particles will often have multiple ways of decaying, each with its own associated probability. Decays are mediated by one or several fundamental forces. The particles in the final state may themselves be unstable and subject to further decay.

What is the Lorentz factor of particle decay?

Particle decay is a Poisson process, and hence the probability that a particle survives for time t before decaying is given by an exponential distribution whose time constant depends on the particle’s velocity: is the Lorentz factor of the particle.
