RESUMO

Some properties of quark chemistry are obtained by performing accurate ab initio Hartree-Fock calculations on fractionally nuclear charged atoms and molecules formed by these atoms. Ground and first excited states of sodium, lithium, beryllium and magnesium atoms with quarks attached to the nucleus are obtained. It is suggested that the electronic transition can be used as a guide in searching for free quarks. The variation of binding electronic energy with nuclear charge in the isoelectronic series of fractionally nuclear charged atoms AÂ2/3 and AÂ1/3 (A = H, Li, Na, P and Ca) is analyzed. It is found that unconfined colored particles prefer to bind with heavy atoms and that quark-antiquark pairs can be stabilized in presence of the atomic matter
