Résumé |
Experiments with exotic radioactive beams often use reactions in which one nucleon
is transferred between target and projectile as a tool to study spectroscopic strength
of nuclear states. The information obtained, such as spectroscopic factors and
asymptotic normalization coefficients, can be used, for example, to predict rates
of nuclear reactions in various stellar environments. This information is obtained
through comparison of the experimental cross sections with theoretical predictions.
It is therefore important to have adequate theoretical models that take the most
important physics of these reactions into account. \newline
In this talk I will present the latest theoretical developments for a particular class
of transfer reactions, deuteron stripping reactions $( d, p )$ - one of the most popular
tools for structure studies - and discuss their uncertainties. I will concentrate on
recent advances in treating nonlocality of nucleon optical potentials within three-
body description of these reactions, the role of the 3N force in the distorted wave
amplitude and a microscopic approach to calculating one-nucleon removal overlap
functions with correct asymptotic behaviour crucial for transfer reactions. |
