Deuteron-stripping reactions at high energy

Naively, one might expect an unsubtracted dispersion relation in u, and then assuming that the E-N anomalous cut saturates the dispersion integral. In this approach, the absolute scale of the amplitude is calculable, whereas before it was left as a free parameter. The calculated normalization turns out to be somewhat larger than the experimental value, and to improve on this would require a much deeper understanding of the deuteron structure.

“…For the last few decades, elastic scattering of deuterons by protons at the backward angle at intermediate energies has intensively been studied as an important source of information of nuclear interactions and reaction dynamics, by including non-nucleonic degrees of freedom in the consideration [1,2,3,4,5,6,7,8,9,10]. Since 3 He has the same spin as the proton's, the spin structure of the scattering amplitude of the d+ 3 He (d 3 He) system is similar to that of the d+p (dp) one when 3 He is considered as a single body [11].…”

Full determination of the dp backward elastic scattering matrix element

“…In the model of Kerman and Kisslinger [2] the dp backward elastic peak is interpreted as due to the admixture of the NN * (1688) state in the standard deuteron wavefunction. The cross section of the dp → pd process was calculated in the framework of the twostep model in which the cross section of the dp backward elastic scattering is expressed in terms of the pp → dπ + cross section [3][4][5]. Such a mechanism leads to a resonant behaviour of the cross section at energies near T p ∼ 600 MeV.…”
