Abstract
A study concerning the valence space dependence of neutrinoless doubleβ− decay observables is performed for several nuclei in the framework of QRPA using the multiple commutator method (MCM). Calculations and comparison to earlier results show that at least for the ground state to ground state transition the dependence is much weaker than in the two neutrino doubleβ− decay. It is still a difficult task to extract the parameters of the neutrinoless doubleβ− decay since the half-life expression contains products of the parameters 〈mν〉 〈η〉 and 〈λ〉.
