Breakup of deuterons on tritons

Microscopic description of diffractive deuteron breakup by 3He nuclei

“…and the nucleon-nucleon profile functions in the form [9] The dash-dotted curves in Fig. 3 were borrowed from [11]; these cross sections were calculated on the basis of the four-body scattering model [20], whose equations were used to describe deuteron breakup according to the 3 He + d → p + d + p + n scheme with allowance for single collisions exclusively.…”

“…We note that, in [9], the diffraction model of multiple scattering was already used to describe the breakup reaction 3 H(d, p)n 3 H . The approach proposed in [9] is formally microscopic because it is based on nucleon-nucleon interactions, but the authors of that study used profile functions including free parameters and replaced the deuteron wave function by a simple Gaussian function, which do not reproduce the asymptotic behavior of the nuclear density at large nucleon-nucleon distances.…”

“…Since the cross sections for deuteron-breakup reactions (in just the same way as those for deuteron-stripping reactions) are sensitive to the behavior of the deuteron wave function in the region of its tail [10], one can consider the results obtained in [9] as quite approximate ones.…”

“…The dashed curves in Fig. 3 represent the results of the calculations with the simple model deuteron wave function ϕ 0 (r) = 2λ π 3/4 exp(−λr 2 ) (21)and the nucleon-nucleon profile functions in the form[9]…”
