The transition probability, l, is also called the decay probability and is related to the mean lifetime t of the state by l = 1/t. The general form of Fermi's golden rule can apply to atomic transitions, nuclear decay, or scattering.

Why the concept of trajectory is meaningless in quantum mechanics?
Because there are no definite positions. There are only probability distributions.
Can anyone explain the quantum theory?
Richard Feynman stated once that "if you think you understand quantum mechanics then you don't understand quantum mechanics". However it is possible to learn how to write and solve the equations of quantum mechanics to get answers that can be verified experimentally.
Is Quantum Mechanics more important than Relativity?
Quantum mechanics and relativity are both parts of the same puzzle: how the universe works. They are both equally important, because they both explain things that are not explained by classical physics.
What is a mixed state in quantum mechanics?
The mixed state in quantum mechanics is the statistical ensemble of the pure states.
When did neils borh contribute to quantum mechanics?
In 1913 he gave us the Bohr Model to explain the Rydberg formula for spectral emissions.
Why plasma is not explained with quantum mechanics?
I am not aware of it "not being explained". I would guess that you can explain the relevant aspects with quantum mechanics.
Why did schrodinger use probability?
Erwin Schrödinger was a physicist and a father of quantum mechanics. Quantum mechanics deals a lot with probability. His famous Schrödinger equation, which deals with how the quantum state of a physical system changes in time, uses probability in how it deals with the local conservation of probability density.

Does quantum and wave mechanics deal with matter?
Yes, as well as other things. Quantum mechanics (also called wave mechanics) is the only approach that can accurately predict the probability of where and in what state matter will end up, given certain initial conditions.
What is the division of mechanics in physics?
the classification of mechanics are:- # Classical Mechanics # Statistical Mechanics # Quantum Mechanics
Quantum mechanics can be used to calculate the probability of an electron's what at any given time?
An electron's location or momentum, but not both.
What is necessary for you to be able to explain what happens during radioactive decay?
To fully explain radioactive decay you need quantum mechanics.
What is the density matrix?
The density matrix refers to the quantum mechanical analogue to a phase space probability measure in the classical statistical mechanics.
When was Principles of Quantum Mechanics created?
Principles of Quantum Mechanics was created in 1930.
