An investigation for the modification of the quasi-adiabatic theory of deuteron break-up

Özet

Recent calculations using the quasi-adiabatic approximation have yielded significant corrections to the adiabatic model and led to an improved description of the measured observables in the $^{66}Zn(d,.p)^{67}Zn$ reaction at 88.2 MeV, due to the sensible choice of the n-p center-of-mass energy in break-up configurations. In this paper, an alternative theoretical approach is suggested to further improve the description of the center-of-mass motion of the n-p pair, by introducing a more consistent prescription for the continuum n-p center-of-mass energy within the quasi-adiabatic formalism. However, its application to the $^{66}Zn$ + d system at 88.2 MeV has shown that such a prescription cannot be used in the analysis of deuteron involving reactions.
