    "abstract": "An enhancement of antiprotons produced in p+d reaction in comparison with\nones in p+p elementary reaction is investigated.\n  In the neighborhood of subthreshold energy the enhancement is caused by the\ndifference of available energies for antiproton production. The cross section\nin p+d reaction, on the other hand, becomes just twice of the one in elementary\np+p reaction at the incident energy far from the threshold energy when\nnon-nucleonic components in deuteron target are not considered.",
