摘要
The binding energy of nuclear matter is calculated in the framework of the Brueckner-Bethe-Goldstone formalism at the two-hole line level of approximation, with the Gamow separable representation of the Argonne upsilon-14 potential. The results are compared with the ones obtained from the original local potential in the "gap choice". The agreement is around 2% for the total potential energy per particle, while for some individual channel the agreement is slightly worse, not exceeding 5%. The same calculation made within the "continuous choice" is very close to the result obtained with the Paris potential, thus confirming the equivalent behaviour of the two potentials in many practical applications.
