Question

The total number of accessible states of n non interacting particles of spin 1/2 is

Answer 1

is the fermionic state

Answer 2

The total number of accessible states of n non interacting particles of spin 1/2 is equal to N.

Explanation:

• The Pauli exclusion principle states that in a single atom no two electrons will have an identical set or the same quantum numbers (n, l, ml, and ms)
• To put it in simple terms, every electron should have or be in its own unique state (singlet state)
• However, Pauli’s Exclusion Principle does not only apply to electrons. It applies to other particles of half-integer spin such as fermions.

• Therefore , Particles which exhibit odd electrical spins are known as fermions .
• Hence , The total number of accessible states of non-interacting particles of spin 1/2 is given that N .
