Using powerful accelerators and cutting-edge detection technologies, the team successfully synthesised Sg-257, a superheavy element not found in nature. The discovery helps answer fundamental questions about how atoms behave at the limits of stability, contributing directly to the international scientific quest for the “island of stability”, a zone in the  nuclear landscape where superheavy elements could have longer, usable lifespans.

“This discovery is an important step in nuclear physics. It helps us understand why some elements survive longer and how nuclear forces behave in extreme conditions,” said Prof. M. Maiti, IIT Roorkee, who was part of the international research team.

“This landmark discovery shows India’s growing role in cutting-edge nuclear research. IIT Roorkee is proud to be part of such global scientific milestones. It echoes our vision of pursuing excellence in fundamental science that benefits society and inspires the next generation,” said Prof. Kamal Kishore Pant, Director, IIT Roorkee.

The research was carried out by an international team of scientists, including Dr. M. Maiti from IIT Roorkee, along with experts from GSI Helmholtz Centre, Germany; Johannes Gutenberg University (JGU Mainz); the Japan Atomic Energy Agency; University of Jyväskylä, Finland; and other collaborating institutions. The findings were published in Physical Review Letters (June 2025) as part of the FAIR Phase-0 collaboration hosted by GSI Helmholtz, Germany.

This discovery exemplifies how fundamental science contributes to technological advancement and global knowledge. It also reflects IIT Roorkee’s enduring commitment to excellence in research that advances theoretical understanding and holds the potential to shape the future of technology, industry, and society.
