Relativistic effects in the nucleon momentum distribution in the deuteron

The authors demonstrate that though some relativistic effects in the nucleon momentum distribution in the deuteron are important in the momentum region k>0.3 GeV/c, these effects can nevertheless not account for the discrepancy between the experimentally measured distribution and the results of theoretical calculations based on two-nucleon wavefunctions. Apart from this, the role of the P wave in the nucleon momentum distribution in the deuteron is discussed.
