    "abstract": "We present a new theoretical approach to describe the quantum behavior of a\nmacroscopic system interacting with an external irradiation field, close to the\nresonant condition. Here we consider the extremely underdamped regime for a\nsystem described by a double well potential. The theory includes both:\ntransitions from one well to the other and relaxation processes. We simulate\nresonant phenomena in a rf-SQUID, whose parameters lie in the range typically\nused in the experiments. The dependence of the transition probability W on the\nexternal drive of the system $\\phi_x$ shows three resonance peaks. One peak is\nconnected with the resonant tunneling and the two others with the resonant\npumping. The relative position of the two peaks correlated to the resonant\npumping depends on the pumping frequency $\\nu$ and on the system parameters.\nThe preliminary measurements on our devices show a low dissipation level and\nassure that they are good candidates in order to realize new experiments on the\nresonant phenomena in the presence of an external microwave irradiation of\nproper frequency.",
