The ground state ofnucleus has spin-paritywhile the first excited stat...
The parity or space inversion operation converts a right-handed coordinate system to left-handed:
x → −x, y → −y, z → −z.
This is a case of a noncontinuous operation, i.e. the operation cannot be composed of infinitesimal operations.
The symmetry operations we require that π is unitary, i.e.
π†π=1
Explanation:
No parity change; ΔJ = 2, 3
For El = type, Δπ = (-1)l (for no parity change l = 2)
For Ml type, Δπ = (-1)l+1 (for no parity change l = 3)
ΔJ = 2, No parity change → E2; ΔJ = 3,
No parity change → M3.
