LigPrep of Schrodinger can generate stereoisomers consistent with specified stereochemical information (e.g. parities in SD files) by varying the chirahties of the atoms for which chirahties are missing. Alternatively, the chirahties of aU chiral atoms may be varied. 

Below we use the RMF model which previously has been successfully applied for describing ground states of nuclei at and away from the )3-stability line. For nucleons, the scalar and vector potentials contribute with opposite signs in the central potential, while their sum enters in the spin-orbit potential. Due to G-parity, for antiprotons the vector potential changes sign and therefore both the scalar and the vector mesons generate attractive potentials. 

To estimate uncertainties of this approach we use three different parameteri-zations of the model, namely NL3 [46], NL-Z2 [47] and TMl [48]. In this paper we assume that the antiproton interactions are fully determined by the G-parity transformation. 

On analysing the J/ multipion decay modes (Tirippe et cd., 1977), it turns out that the J/ decays approximately ten times more frequently into an odd than into an even number of pions. Both types of decay, however, do occur. Since pions have G parity (-1) and as a consequence the G parity of a non-strange neutral meson should be even or odd according to whether it decays into an even or odd numbers of pions, we might conclude that G is not a good quantum number for J/9 decay. 

It is thus not unreasonable to assume that J/9 has a definite (negative) G parity and that while the direct decay [Fig. 11.9(a)] is G parity conserving the one-photon contribution [Fig. 11.9(6)] gives the observed violation of G parity. To check this, we notice that, off resonance, the ratio of the one photon contribution to multipion final states and to pairs must be insensitive as to whether the multipion final states have an even or an odd number of pions. Thus, a plot of... 

Similarly, the conversion factor between the 3G and 87 decay involves a sum over colour indices of the trace of the symmetric combination of AaAaAc which is the only one to have negative G-parity as was pointed out in Section 11.6. One has then... 

Thus the G-parity of an n-pion state is (—1)", and this leads to various selection rules for hadronic reactions. 

Synthesis results. The ECC was synthesized and mapped to cells in LSI Logic s LCAIOK library. Two experiments were performed to illustrate the effect of resource sharing. In the first experiment, the hardware resources implementing PARITY.3 and PARITY-4 were assumed to have small area cost. This assumption corresponds to the actual implementation of these resources based on their HardwareC description, e.g. PARITY 3 is a three bit XOR and PARITY-4 is a four bit XOR. In the second experiment, the area cost for these resources was increased ten-fold to demonstrate the case where the area reduction due to sharing resources outweighs the area increase due to multiplexers and latching registers. Synthesis results of these experiments are summarized in Table 11.9.
