Abstract. We present a brief introduction to the second order DWBA reaction formalism which we have used to perform the theoretical analysis of two-nucleon transfer reactions induced both by heavy and light ions. We also show an example of such a calculation, emphasizing the connection between the structure aspects of the problem and the resulting predicted two-neutron transfer cross section. The calculations were carried out making use of software specifically developed for this purpose. It includes sequential, simultaneous and non-orthogonality contributions to the process. Microscopic form factors are used which take into account the relevant structure aspects of the process, such as the nature of the single-particle wavefunctions, the spectroscopic factors, and the interaction potential responsible for the transfer. Overall agreement with the experimental absolute values of the differential cross section is obtained without any free parameter.

World Scientific Review Volume -9.75in x 6.5in 120507˙˙more˙is˙diff 2 R.A. Broglia acids occurring in nature, and the associated symmetry breaking in information (sequence) space. Emergent properties of the corresponding phase transition are domain walls which stabilize local elementary structures (LES), few groups of 10-20 aminoacids which become structured already in the denatured state with varied degree of stability, and which can be viewed as (mutually complementary) virtual secondary structures providing the molecular recognition directing protein folding under biological conditions (solvent, temperature, pH, etc.). In fact, their docking is closely related to the transition state of the process. While the two-step, yes or no, folding process, does not provide direct information concerning LES, one can force LES from virtual to become real, observable final state entities. Getting again inspiration from the nuclear case (virtual processes contributing to pair correlations can be forced to become real with the help of a probe which itself changes particle number by two), one would expect that to make real virtual LES, that is segments of the protein which already at an early stage of the folding process flicker in and out of their native conformation, one needs a probe which itself displays a similar behaviour. It is almost self-evident that peptides (p-LESi) displaying a sequence identical to LESi will bind with high specificity to its complementary LESj, blocking folding and exposing the (p-LES)i-LESj complex to direct observation. Results in vitro and ex vivo (infected cells) of the folding inhibition ability of p-LES, testify to the soundness of the picture. Based again on the analogy with the nuclear case (become theoretically and experimentally quantitative in the prediction and measurements of Cooper-pair tunneling), much effort has been concentrated in defining the new paradigm of protein inhibition, namely folding inhibition, and to develop the in silica protocols, and the wet laboratory activity assays, which quantitatively can map out the role LES play in folding. It is expected that eventually, this insight can help in developing p-LES into leads of non-conventional drugs.

The findings for which Aage Bohr and Ben R. Mottelson became co‐winners of the 1975 Nobel Prize in physics provided the basis for what can be called the second discovery of the atomic nucleus. They found that in this self‐bound microscopic system made out of nucleons, collective and independent‐particle motion, typical of a liquid drop and of planetary motion respectively, emerge from the same components of the strong force, their interweaving leading to phase transitions which can be studied in terms of individual quantal states.
