Atomic recoil Atomic recoil Atomic recoil is the result of the interaction of an atom with an energetic elementary particle, when the momentum of the interacting particle is transferred to the atom as whole without altering non-translational degrees of freedom of the atom. It is a purely quantum phenomenon. Atomic recoil was discovered by Harriet Brooks, Canada's first female nuclear physicist. If the transferred momentum of atomic recoil is enough to disrupt the crystal lattice of the material, a vacancy defect is formed; otherwise a phonon is generated. Closely related to atomic recoil is electron recoil (see photoexcitation and photoionization), and nuclear
Ida (given name) Ida (given name) Ida is a given name occurring independently in several cultures. In Germany, Ida is a female name derived from a Germanic word "id", meaning "labor, work". Alternately, it may be related to the name of the Old Norse goddess "Iðunn". Ida also occurs as an anglicisation of the Irish girl's given name Íde.
