We analyse the effects that different nuclear structure approximationsassociated with the short range correlations (SRC), finite nucleon size (FNS),higher order terms in the nucleon currents (HOC) and with some nuclear inputparameters, have on the values of the nuclear matrix elements (NMEs) for theneutrinoless double beta (0{\nu}{\beta}{\beta}) decay. The calculations areperformed with a new Shell Model(ShM) code which allows a fast computation ofthe two-body matrix elements of the transition operators. The treatment of SRC,FNS and HOC and include the use of quenched or unquenched values for the axialvector coupling constant produce the most important effects on the NMEs values.Equivalent effects of some of these approximations are also possible, which maylead (accidentally) to close final results. We found that the cummulativeeffect of all these nuclear ingredients on the calculated nuclear matrixelements NMEs is significant. Since the NMEs values are often obtained withdifferent approximations and/or with different input parameters, a convergentview point on their inclusion/neglection and an uniformization of thecalculations are needed, in order to enter in an era of precision concerningthe computation of the NMEs for double beta deacay.
