Nuclear Magnetic Moment - Electromagnetic Moment

Japanese: 核磁気モーメント - カクジキモメント
Nuclear Magnetic Moment - Electromagnetic Moment

This refers to the magnetic moment of an atomic nucleus. If the sum of the orbital angular momentum of the nucleons that make up the nucleus is L and the sum of their spins is S , then the total angular momentum I of the nucleus is

I = L + S
In atomic nuclei, this I is usually called the nuclear spin. If the number of nucleons is even, the nuclear spin I is 0 or an integer, and if the number is odd, it is a half-integer. The nuclear magnetic moment μ is due to this nuclear spin I , and the relationship between the two is

μ = g μ N I
Here, μN is the unit of magnetic moment called the nuclear magneton, and g is the nuclear g-factor.

Japanese:

原子核がもつ磁気モーメントをいう.原子核を構成している核子の軌道角運動量の和をL,スピンの和をSとすると,原子核の全角運動量I

ILS
であるが,原子核では普通このIを核スピンとよぶ.核スピンIは核子の数が偶数ならば0または整数,奇数ならば半整数の値をとる.核磁気モーメントμはこの核スピンIによるもので,両者の間は

μ = gμNI
で結ばれる.ここで,μN は核磁子とよばれる磁気モーメントの単位であり,gは核のg因子である.
