Quasi-Elastic $d(\vec{p}, \vec{n})2p$ Reaction and Spin Response Functions of the Deuteron

Abstract

We calculated response functions of the deuteron for charge exchange processes, including the final state interaction between two protons. Using them we evaluated the double differential cross section and polarization observables of d( p, n)2p by means of plane wave impulse approximation with an optimal factorization. Calculation well reproduced the shape of the energy spectra of the cross section, though somewhat overestimated the magnitude. It also reproduced the spin observables well.

“…3. The data have been compared with the theoretical predictions obtained through PWIA using the computer code dpn [23]. These calculations have reproduced the previous 2 H(p, n) data at T p = 345 MeV and θ lab = 16…”

Polarization transfer and spin response functions of theH2(p⃗,n⃗)reaction

“…The solid curves in Fig. 3 represent the theoretical spin response functions calculated with the program code of Itabashi, Aizawa, and Ichimura [4]. The theoretical calculations can reproduce the shape of both spinlongitudinal and spin-transverse response functions very well, while the magnitude is somewhat underestimated, es-pecially for R T .…”

“…The PWIA calculations for the 2 H͑p , n͒ reaction were performed with the code developed by Itabashi, Aizawa, and Ichimura [4]. The initial deuteron and final pp-scattering wave functions are generated by the Reid soft core potential.…”

“…Thus we compare our data with plane-wave impulse approximation (PWIA) calculations [4], employing the optimal factorization approximation [5][6][7][8] to access the accuracy of these approximations. Furthermore, the agreement between the experimental and theoretical results measures the dominance of the one-step quasielastic process assumed in the calculations.…”

“…One possibility is the effects of the D-state in 3 He. The deuteron D-state effects for 2 H(p, n) at the same incident energy were studied by Sakai et al [9] using the plane wave impulse approximation code developed by Itabashi et al [27]. They concluded that the effects to the cross section at θ lab = 0…”
