Angular momentum projection integrals for coherent states
Serdar Kuyucak, Koniparambil Pappu Unnikrishnan · Journal of Physics A Mathematical and General · 1995
Angular momentum projection integrals arising from the coherent state representation of bosonic spectrum generating algebras are evaluated using analytical and algebraic methods. For the vibron model of diatomic molecules, a closed expression is derived by direct integration. For the general case, the integral is evaluated as a 1/N expansion by exploiting the symmetries of the underlying boson system and making use of computer algebra.
