Pushing the Boundaries of the Periodic Table: Berkeley Lab’s Quest for Element 120

The quest to understand the fundamental building blocks of matter has led scientists on an extraordinary journey through the periodic table. For decades, researchers have been driven by the challenge of synthesizing new elements, especially superheavy elements – those with atomic numbers greater than 104. Now, a team at the Lawrence Berkeley National Laboratory (Berkeley Lab) has made a significant leap forward, demonstrating a novel method to create element 116 (livermorium) using a titanium particle beam – a first for Berkeley Lab. This breakthrough opens the door to a future where scientists could potentially produce element 120, bringing us closer to the theoretical island of stability – a theorized region where superheavy elements could have longer lifespans.

A Titanium Beam Forges a New Element

The team achieved this groundbreaking feat by bombarding a plutonium target with a high-energy beam of titanium-50 – a specific isotope of titanium. This precise targeting unleashed a cascade of reactions within the plutonium nuclei, ultimately leading to the creation of livermorium atoms. The feat is particularly noteworthy because it marks the heaviest element produced at Berkeley Lab to date. Their pioneering work in heavy element synthesis can be traced back to the 1950s, with their team involved in the discovery of 16 elements, from technetium (43) to seaborgium (106).

"We’re very confident that we’re seeing element 116 and its daughter particles," said Jacklyn Gates, a nuclear scientist at Berkeley Lab and leader of this project. "There’s about a 1 in 1 trillion chance that it’s a statistical fluke."

The process of producing this elusive element is a testament to the ingenuity and perseverance of the researchers. They started with a solid piece of titanium, transforming it into a beam through a multi-step process. First, the titanium was heated to nearly 3,000 degrees Fahrenheit (1,649 degrees Celsius), causing it to vaporize. This vapor was then bombarded with microwaves, stripping away 22 electrons from each titanium atom. These highly charged ions were then accelerated to tremendous speeds within Berkeley Lab’s renowned 88-Inch Cyclotron, a powerful particle accelerator.

"When we’re trying to make these incredibly rare elements, we are standing at the absolute edge of human knowledge and understanding, and there is no guarantee that physics will work the way we expect," emphasized Jennifer Pore, a nuclear physicist in Berkeley Lab’s heavy element group.

The team’s success hinges on a crucial element: fusion. The high-velocity titanium ions, each carrying a positive charge, were aimed at a target of plutonium atoms. This bombardment resulted in trillions of collisions per second, providing a minuscule chance for the titanium and plutonium nuclei to fuse together, creating a new, heavier element. The researchers were able to produce two livermorium atoms over a period of 22 days – a remarkable feat given the sheer rarity of the process.

This study marks a new milestone in heavy element synthesis. Traditionally, elements 114 through 118 were created using a calcium-48 beam. The successful use of a titanium beam demonstrates the versatility of this method, opening up possibilities for the creation of even heavier elements.

The Pursuit of Element 120: The "Island of Stability"

The creation of livermorium is not merely a scientific curiosity; it is a stepping stone towards a grander goal: the pursuit of element 120, the heaviest atom yet to be synthesized. The team’s next pursuit lies in pushing the boundaries of nuclear physics, venturing into the uncharted territory of the periodic table.

Element 120 holds a special significance – it is predicted to exist within the island of stability. According to theoretical models, this hypothetical region of the periodic table should encompass elements with unusually long half-lives, far exceeding those of the superheavy elements discovered so far. This unusual stability stems from a balance between the strong nuclear force that holds atomic nuclei together and the repulsive electrostatic force between the positively charged protons.

The pursuit of element 120 is not just about adding another element to the periodic table. It would present a unique opportunity to study the interplay of forces that govern the stability of atomic nuclei, providing crucial insights into the very nature of matter. It could also pave the way for exploring the potential applications of these superheavy elements, ranging from novel materials to advancement in nuclear energy.

A Glimpse into the Future of Nuclear Physics

The Berkeley Lab scientists are set to embark on their hunt for element 120 in 2025. This ambitious project promises to be a long and challenging journey, potentially spanning several years. It requires a meticulous combination of theoretical calculations, experimental ingenuity, and cutting-edge technology.

The pursuit of element 120 represents a compelling testament to humanity’s relentless drive to explore and understand the universe. It is a reminder that even at the very edge of our current understanding, there are still frontiers to be explored, mysteries to be unraveled, and discoveries waiting to be made. As these researchers journey towards the island of stability, they are pushing the boundaries of our knowledge, not just about the atom, but also about the limits of what we can achieve in the pursuit of scientific discovery.
