“…Although it is rarely used in nuclear calculations, the Padua NN potential is a serious try to find an even more sensible NN potential. For other interesting theoretical and numerical analyses in their method, see the original paper [46].…”

“…Nowadays, it is almost clear that the meson-exchange potentials (MEP's) are almost the standard NN potentials. Some examples are the Partovi-Lomon model [35], and Stony Brook-group [43], Paris-group [44], Bonn-group [45], Padua-group [46], Nijmegen-group [28] and Hamburg-group [47] potentials. Boson-exchange methods are nowadays extended, besides NN systems, to many Baryon-Baryon (BB) interactions such as pion-nucleon, pion-pion, Hyperon-Nucleon (YN) and Hyperon-Hyperon (YY) interactions as well.…”

Nearly a recent century of work is divided to Nucleon-Nucleon (NN) interaction issue. We review some overall perspectives of NN interaction with a brief discussion about deuteron, general structure and symmetries of NN Lagrangian as well as equations of motion and solutions. Meanwhile, the main NN interaction models, as frameworks to build NN potentials, are reviewed concisely. We try to include and study almost all well-known potentials in a similar way, discuss more on various commonly used plain forms for two-nucleon interaction with an emphasis on the phenomenological and meson-exchange potentials as well as the constituent-quark potentials and new ones based on chiral effective field theory and working in coordinate-space mostly. The potentials are constructed in a way that fit NN scattering data, phase shifts, and are also compared in this way usually. An extra goal of this study is to start comparing various potentials forms in a unified manner. So, we also comment on the advantages and disadvantages of the models and potentials partly with reference to some relevant works and probable future studies. * E-Mail: m.naghdi@mail.ilam.ac.ir

“…Still, there are some other typical potentials that we address briefly in the next paragraph. The Padua-group NN potential [22], which is based on meson-exchange theory by employing the phenomenological terms, describes the phase shifts and deuteron properties similar to the Paris80 [45], Arg84 [34] and Bonn-A [44] potentials. The Virginia-group potentials [25], as some special relativistic OBE models, have almost the same quality to fit the data as the Bonn87 [21] and Arg84 [34] potentials.…”

“…Most potentials in this category always employ the field-theoretical and dispersion-relations techniques. Among the first versions are Partovi-Lomon model (first in [16]), Stony Brook-group' potential (first in [17]), the super-soft-core potentials (first in [18]), Funabashi potentials (first in [19]), Paris-group (first in [20]), Bonn-group (first in [21]), Padua-group (first in [22]), Nijmegen-group (first in [23]) and Hamburg-group (first in [24]) potentials. The typical potentials such as the Virginia-Group potential [25], the Bochum-Group potential [26] and Tubingen-Group [27] are also mentionable.…”

The aim is to compare a few Nucleon-Nucleon (NN) potentials especially Reid68, Reid68-Day, Reid93, UrbanaV14, ArgonneV18, Nijmegen 93, Nijmegen I and Nijmegen II. Although these potentials have some likenesses and are almost phenomenological, they include in general different structures and their own characteristics. The potentials are constructed in a manner that fit the NN scattering data or phase shifts and are compared in this way. A high-quality scale of a potential is that it fits the data with χ 2 /N data ≈ 1, describes well the deuteron properties and gives satisfactory results in nuclear-structure calculations. However, these scales have some failures. Here, we first compare many potentials by confronting them with the data. Then, we try to compare the potential forms by considering the potential structures directly and therefore regarding their substantial bases somehow. To do so, we note that since the potentials are written in different schemas, it is necessary to write them in a unique schema. On the other hand, because three major terms in the NN interaction are central, tensor and spin-orbit terms; so, to perform a reduction plan and arrive at a common structure, we choose the Reid's potential form. Next, we compare the potentials for some states and address some other related issues as well. *
