The person who is engraved with the

Years of not seeing him again, but the image of this world-famous physicist is still imprinted in the memory of the writer from the first meeting, 45 years ago, at the Institute of Nuclear Research (JINR) at Dup na, Russia.

An erudite broad forehead, determined and assertive eyebrows, sharp and sharp eyes, witty and friendly mouth.

It can be said that the aforementioned human spirit and intellectual characteristics converge in him, "honoring" him on the most glorious steps in the scientific castle of Russia and humankind.

The scientific world today refers to him, first of all, as the father of the Russian (or the former Soviet) scientific school of super-heavy or super-heavy elements, the founder of the County Reaction Laboratory. named Flerov belongs to JINR (1957).

Here, under his direction, it has successfully synthesized a series of previously unknown superheavy elements that have never been found in the natural world, such as: Nobelium (with Z = 102). , Lawrencium (103), Rutherfordium (104), Dubnium (105), Seaborgium (106), Bohrium (107) and, in particular, Flerovium (114).

Flerov Georgy Nikolaevich

And so, after the only case of Seaborg, the father of science science super-heavy elements with the element Seaborgium (106), in turn the next survivor Flerov is engraved with the 'golden name' in the 114th box of The periodic table of chemical elements, with the chemical name Flerovium, follows the latest May 31, 2012 decision by the International Association of Basic Chemistry and Applications IUPAC.

Inventing history

Having had an opportunity to interact with Georgy Nikolaevich, listening to his presentation of scientific research projects or achievements, I felt and deeply impressed with his scholarship, his deep understanding of not only physics. the nucleus, which is also in terms of super uranium element chemistry, heavy ion accelerator technology .

That quality has served as a fulcrum for this nuclear scientist to achieve the early scientific achievements, receiving patents since he was a young graduate student at the Leningad Institute of Physics.

It was the talented young physicist Flerov, in 1940, who was one of the two authors of the invention of historical significance for a new type of radioactive change, ie ' Spontaneous division of uranium nucleus' , public Official father of the two articles "Spontaneous division of uranium" and "Spontaneous division of thorium" in the Journal of LX Sciences' Reports.

Suspicious silence and the letter to Stalin

GN Flerov's innate sharp thinking revealed from the young, during the Great Patriotic War of Soviet Russia. Many people in the Vietnamese science group at the Institute of na na in the 1960s, had the opportunity to hear him recounting it himself as a veteran.

In 1942, the commander of the tank, Georgy Flerov, was sent to the front. And it was from the front that he sent a letter to Marshal Stalin, which explained why it was necessary to build an atomic bomb, and how to build it.

Flerov made a very sharp comment to prove that western experts are secretly researching the creation of this terrible weapon. It was an unexpected silence, a sudden cessation of the publication of all the results of their research.

Not knowing how much the letter worked, but soon after receiving reports from the Lon Don spies sent to the west that the west had begun to build bombs, a Soviet decision to create an atomic bomb immediately given.

Element 105 and aircraft F105

In the 60s of the last century, the hunt for superheavy elements in the Nuclear Reaction Laboratory (Double Na) was very exciting, especially with elements 103, 104 and 105. The same period that, the air war in northern Vietnam, especially in Hanoi and Hai Phong . took place very fiercely with many US Air Force F105 aircraft being shot down.

Now, it is GN Flerov that offers a unique physical idea, assuming that in the earth's crust, super-heavy elements can exist from creation. Because of the long life span of hundreds, thousands or millions of years, and due to the spontaneous division of these rare elements, super heavy nuclei can leave traces in ancient rock samples. or lying on the ocean floor, especially in specimens of ancient artifacts.

So, it was Flerov who made the bold initiative, mobilizing as many people as possible to find traces of the super-heavy element in an ancient object with a microscope. And the Youth Union of young Vietnamese collaborators at the Institute of Double Na responded, turning some socialist Saturdays into the Saturday competition to find new elements in Flerov's Laboratory.

Everyone jokingly calls the race to find element 105 to shoot F105 aircraft! In the end, no one in our branch that day 'shot ' the F105 . Simply because of the presence of super heavy elements on the Earth's crust, if true, it is also extremely rare, looking for them is like searching for a needle at the bottom of the sea.

However, it is also a meaningful entertainment, especially an interesting memory. It shows that, with a true scientist, looking in the environment also sees 'love' , natural 'elements' as objects, or catalysts for inspiring research and tremendous creativity. .

After this event, we got to know more, besides a world-renowned physicist and brilliant Flerov, a Russian man, an ordinary Nikolai; funny and friendly with international friends, especially with young researchers from the warring country of Vietnam.
