Their local form, in configuration space, derived in Ref. [10], is W$_{D}$ (1 , 2 , 3) = W D 0 ( $^{τ}$1 · $^{τ}$2 ) { ( $^{σ}$1 · $^{σ}$2 )[ y ( r 31 ) Z 0 ( r 23 ) + Z 0 ( r 31 ) y ( r 23 )] + ( $^{σ}$1 · $^{r}$31 )( $^{σ}$2 · $^{r}$31 ) t ( r 31 ) Z 0 ( r 23 ) + ( $^{σ}$1 · $^{r}$23 )( $^{σ}$2 · $^{r}$23 ) Z 0 ( r 31 ) t ( r 23 ) } W$_{E}$ (1 , 2 , 3) = W E 0 ( $^{τ}$1 · $^{τ}$2 ) Z 0 ( r 31 ) Z 0 ( r 23 ) . (9) The constants W D 0 and W E 0 fix the strength of these terms. In the case of the URIX model the D -term is absent whereas the E -term is present without the isospin operatorial structure and it has been included as purely phenomenological, without justifying its form from a particular exchange mechanism. Its radial dependence has been taken as Z 0 ( r ) = T $^{2}$( r ). In the N2LOL model, the function Z 0 ( r ) is defined as Z 0 ( r ) = 12 π m 3 π 1 2 π 2 ∫ ∞ 0 dqq $^{2}$j 0 ( qr ) F Λ ( q ) (10) with the same cutoff function used before, F Λ ( q ) = exp( − q $^{4}$/ Λ $^{4}$). In the TM’ model the D - and E -terms are absent. Each model is now identified from the values assigned to the different constants. Following Refs. [5, 24], in the case of the TM’ model, the values of the constants are a = − 0 . 87 m − 1 π , b = − 2 . 58 m − 3 π , and d = − 0 . 753 m − 3 π ; the strength W 0 = ( gm$_{π}$/ 8 πm$_{N}$ ) 2 m 4 π and the cutoff has been fixed to Λ = 4 . 756 m$_{π}$ in order to describe correctly, associated to AV18, B ( $^{4}$He). In Table I the calculations have been done using these values with g 2 = 197 . 7, m$_{π}$ = 139 . 6 MeV, m$_{N}$/m$_{π}$ = 6 . 726 ( m$_{N}$ is the nucleon mass) as given in the original derivation of the TM potential. In the URIX model the b - and d -terms are present, however with a fixed ratio based on the Fujita-Miyazawa diagram. The strength of these terms are: bW 0 = 4 A PW 2 π and d = b/ 4, with A PW 2 π = − 0 . 0293 MeV. The model includes a purely central repulsive term introduced to compensate the attraction of the previous term, which by itself would produce a large overbinding in infinite nuclear matter. It is defined as with A$_{R}$ = 0 . 0048 MeV. In the N2LOL potential the constants of the a -, b -, d -, D - and E -terms are defined in the W URIX E (1 , 2 , 3) = A$_{R}$T $^{2}$( r 31 ) T $^{2}$( r 23 ) (11) 7
