    "abstract": "The validity of the pn-QRPA and -RQRPA descriptions of double beta decay\ntransition amplitudes is analyzed by using an exactly solvable model. It is\nshown that the collapse of the QRPA is physically meaningful and that it is\nassociated with the appearance of a state with zero energy in the spectrum. It\nis shown that in the RQRPA this particular feature is not present and that this\napproach leads to finite but otherwise spurious results for the double beta\ndecay transition amplitudes near the point of collapse.",
