来曼系 Lyman series

(重定向自Lyman line)
Serie de Lyman
Energieniveaus des Wasserstoffatoms mit nach Serien geordnete Übergänge

莱曼系是物理学上氢原子的电子从主量子数n大于等于2跃迁至n = 1的一系列光谱线。这些系列以希腊字母依序标示:n = 2跃迁至n = 1称为莱曼-α,3跃迁至1称为莱曼-β,4跃迁至1称为莱曼-γ,依此类推。这个串行的谱线是以发现者莱曼命名为莱曼系。

Lyman series 来曼系

(重定向自Lyman line)
Serie de Lyman
Energieniveaus des Wasserstoffatoms mit nach Serien geordnete Übergänge

In physics and chemistry, the Lyman series is a hydrogen spectral series of transitions and resulting ultraviolet emission lines of the hydrogen atom as an electron goes from n ≥ 2 to n = 1 (where n is the principal quantum number) the lowest energy level of the electron. The transitions are named sequentially by Greek letters: from n = 2 to n = 1 is called Lyman-alpha, 3 to 1 is Lyman-beta, 4 to 1 is Lyman-gamma, etc. The series is named after its discoverer, Theodore Lyman. The greater the difference in the principal quantum numbers, the higher the energy of the electromagnetic emission.
