Some Contributions to Neutron Scattering in India and Asia-Oceania Region:1958-2012

National, regional and international cooperation is well known nowadays when it comes to building and using major scientific facilities like nuclear reactors, particle accelerators, space exploration, etc. It was not so when I started my research career in 1958 at Atomic Energy Establishment Trombay (AEET), now renamed Bhabha Atomic Research Centre (BARC). Asia-Oceania Neutron Scattering Association (AONSA) was established some years ago in recognition of this need in the region specified in its name. In the present article I shall deal with some aspects of my contributions to the growth of neutron scattering techniques and science, and highlight how cooperation among various bodies has helped in the growth of science based on neutron scattering.
