I outline the effective field theory (EFT) calculation of nucleon-nucleon scattering which was recently carried out to next-to-next-to-leading order (NNLO) by Noam Shoresh and myself. In this calculation only potential pion contributions are included. These are the leading contributions from pions. A toy model was also considered in which potential pions are the only pion effects. The effective...

We have developed a phenomenological quasi-deuteron model to describe photodisintegration reactions of He and He at intermediate photon energies, and compared the results with experimental data obtained by TAGX group in which contributions from photon absorption by pn pair were selectively observed. The data can be reproduced reasonably well, however there still remain certain discrepancies bet...
