David Brink completed his first degree in Tasmania in 1951 and
submitted his Ph.D. Thesis in Oxford in May 1955. He spent a year at MIT in
1955-56 and was appointed as a Fellow of Balliol College and Lecturer in
Theoretical Physics at Oxford University in 1958. He was elected to a
Fellowship of the Royal Society in 1981 and was awarded the Rutherford Medal
by the Institute of Physics in 1982. For a number of years he was an Associate
Editor of Nuclear Physics. In 1993 he moved to a chair at the University of
Trento in the History of Physics. At the same time he became the Vice-Director
of the European Center for Theoretical Nuclear Physics and Related Areas.
A lifelong interest in the physics of giant resonances began with a project
on the radiative widths of neutron resonances. The widths were estimated by
relating photon emission and absorption and assuming that the cross section
for absorption of a dipole photon by an excited nuclear state would have the
giant resonance form as for absorption by the ground state.
Another long term interest has been the use of semi classical methods for
heavy ion reactions and nuclear structure. In the early 70s David Scott and his
group in Oxford had an experimental programme on the Harwell cyclotron and
found a selectivity in the population of high angular momentum states in heavy
ion transfer reactions. Dr. Brink wrote a paper in 1972 on kinematical effects
in heavy ion reactions which helped to explain this selectivity. This
theoretical idea was developed, especially in collaboration with Hashima Hasan,
Luigi Lo Monaco, Ica Stancu and Angela Bonaccorso. They invented a simple semi
classical model for neutron transfer to bound states. Later Dr. Bonaccorso and
Dr. Brink extended the method to calculate transfer to the continuum processes.
This approach was very successful in accounting for the position and width of
the peak in the breakup cross section. Other applications of semi classical
methods have been to the ALAS phenomenon in alpha scattering with Noboru
Takigawa and to path-integral methods with Dr. Sukumar.
For several years from 1969 Dr. Brink had a very productive collaboration with
Dominique Vautherin, Marcel Veneroni and their collaborators at Orsay on the
use of Skyrme's effective interaction for Hartree-Fock calculations and, later,
on the semi classical theory of collective motion in nuclei. In 1981 this work
was extended in collaboration with Massimo Di Toro into a study of the dynamics
of a semi classical Hartree-Fock fluid and then, with Alberto Dellafiore, into
an investigation of the Vlasov equation which is the classical analogue of the
Hartree-Fock method. In another direction Renzo Leonardi, Sandro Stringari and
David Brink found interesting results by using sum rules with Skyrme's
interaction.
Dr. Brink has always had an interest in nuclear structure problems. His
first paper was on applications of the shell model to nuclei near the 208Pb
magic number. He has studied alpha clustering in nuclei especially in
association with several Japanese groups. Most recently he has written a book
with Ricardo Broglia on the pairing interaction and nuclear superfluidity.
