A poster on "Decay spectroscopy of neutron rich Iodine isotopes", presented by Soumik Bhattacharya of Physics Group, at the “Euro-School on Exotic Beams” held at Padova, Italy, during September 7-13, 2014, has been selected as the 2nd best poster among 56 posters, represented by students from various international laboratories and universities of the world.
“Euro-School on Exotic Beams” is a well known international annual event, supported by several large research facilities and funding agencies in Europe. The school is intended for PhD students and young post-docs working in areas related to radioactive-ion beams and consist of several lecture courses given by experts in the field.
Photograph taken from Soumik’s facebook profile: During a month’s long tour to Europe, apart from attending the Euro-school, he attended TALENT School held at GANIL. In the week end, Soumik didn’t miss to visit Louvre museum and Eiffel tower in Paris with his friends.
The poster, represented by Soumik, is based on the recent experiments carried out at our K130 cyclotron facility using the offline decay spectroscopy of radio-chemically separated fission fragments, produced from fission of 238U target, induced by 32 MeV alpha beams. Fission, being known as one of the best route to produce neutron-rich nuclei in medium mass region, was utilized to produce neutron-rich Iodine isotopes along various other fission products. After radiochemical separation from all other fission products, the clean Iodine samples were counted with a coincidence setup of four Clover HPGe detectors and two segmented Low Energy Photon Spectrometer (LEPS). Various neutron-rich Xenon isotopes, produced from the decay of corresponding Iodine isotopes, were identified and decay gamma rays were measured in coincidence.
