Abstract
The experimental results on the analyzing power T20 in the 12 C( −→ d,p) 13 C ∗ reaction
with excitation of levels of a nucleus 13 C at the energy Td = 140, 200 and
270 MeV for at emission angle Θcm=0 ◦ are presented in this work. The data on
the tensor Ayy, Axx, Axz and vector Ay analyzing powers for the 12 C( −→ d,p) 13 C ∗
reaction at energy Td = 270 MeV in the angular range from 4 ◦ to 18 ◦ in laboratory
system are also obtained.
Introduction
The ( −→ d,p) stripping reaction has proved a useful tool for probing single particle
aspects of nuclear structure. With the advent of beams of exotic nuclei there has been
renewed interest in charged particle spectroscopy and ( −→ d,p) stripping in particular as a
means of investigating the structure of neutron-rich nuclei via reactions in inverse kinematics
[1].
Direct measurement of the capture reactions at energies of astrophysical interest is,
in some cases, nearly impossible due to the low reaction yield, especially, if the capture
involves exotic nuclei. Alternative indirect methods, such as the asymptotic normalization
coefficient (ANC) method, based on the analysis of breakup or transfer reactions,
have been used as a tool to obtain astrophysical S-factors. The advantage of indirect
approaches comes from the fact that transfer and breakup reactions can be measured at
