Abstract
We derive a general formula, using Fermi's golden rule, for the multip honon relaxation rate for a two-level system coupled off-diagonally to a bath of phonons. Our result is valid for any scalar form of the sys tem-bath interaction potential. With our result we analyze experimenta l data involving the energy gap and temperature dependence of electron ic relaxation rates for rare-earth ions in YA1O(3).
