The Moller operators and the asociated Lippman-Schwinger equations obtained from different partitionings of the Hamiltonian for a step-like potential barrier are worked out, compared and related.

The three years since the introduction of 'gastric freezing' by Wangensteen and his associates (Wangensteen, Peter, Nicoloff, Walder, Sosin, and Bernstein, 1962a; Wangensteen, Peter, Bernstein, Walder, Sosin, and Madsen, 1962b; Peter, Bernstein, Sosin, Madsen, Walder, and Wangensteen, 1962) have witnessed a mounting scepticism as regards its safety and efficacy (Mcllrath, Hallenbeck, Allen, Man...

in this paper, using monte carlo fortran code, we have obtained the binding energies for three different systems of diquark–antidiquark in distances from 0.01 to 15 nm. in [0.1 - 15] nm interval, we made use of coulomb potential because in this interval, strong interaction is negligible. we have compared the binding energies of the systems with one another. the results of these comparisons were...
