  a qudt:QuantityKind ;
  dcterms:description "Given two atomic states of energy $E_j$ and $E_k$.  Let $E_j > E_k$.  Assume the atom is bathed in radiation of energy density $u(w)$.  Transitions between these states can take place in three different ways. Spontaneous, induced/stimulated emission, and induced absorption. $A_jk$ represents the Einstein transition probability for spontaneous emission."^^qudt:LatexString ;
