angular momentum, \(L\)
Angular @M04007@, or moment of @M04007@ of a particle about a point is a vector quantity equal to the vector product of the position vector of the particle and its @M04007@, \(L=r\times p\). For special angular momenta of particles in atomic and molecular physics different symbols are used.
