Dr. Padmanabhan Krishnagopalan Iyengar passed away yesterday. He was a former Atomic Energy Commission of India chairman during 1990-93 and Director of Bhabha Atomic Research Centre (BARC), Bombay. He was largely responsible for the Neutron Physics division in BARC. He was deputed by DAE to Chalk River Labs of Canadian Atomic Energy Establishment and worked under nobel laureate Prof. Bertram Brockhouse. They jointly published a series of papers on neutron spectroscopy of Germanium, which was gaining popularity in electronic industry then. Their seminal work lead to great understandings in Germanium.
P.K. Iyengar was very vocal in his opposition to the Indo-US civilian nuclear agreement arguing that the agreement is more favourable to the US than to India and criticizing the role China could have played in strong-arming the International Atomic Commission to include significant favours to nuclear non-entities like New Zealand and Austria.
I was a scientist in Department of Atomic Energy, India in 1996-97 and know the respect and reverence Dr. Iyengar claimed among the colleagues there.
