Magic Numbers in the Nucleus: Fact vs. Fiction

In summary, the conversation discusses the concept of "magic numbers" in relation to the nucleus. The lecturer mentions 114 as a magic number, but the speaker has found conflicting information with 126 being identified as a magic number. The group then discusses how magic numbers become more complex as the number of protons and neutrons increases. It is suggested that both 114 and 126 could be considered magic numbers, but that one model may not be entirely accurate. The idea of 42 being the ultimate answer to life is also mentioned, but it is acknowledged that it may not be well-received without the corresponding question.

I am really not sure and do not understand how you find out what are the magic numbers in case of nucleus. Here in leson

lecturer said that magic number is ##114##, and in other resourses I find number ##126##? Do we have any real confirmation of this?

Magic?

Magic numbers get more messy with increasing number of protons or neutrons. It is possible that both are "a bit" magic, or that one model is not very accurate.
126 seems to be well-established (for neutrons only of course), large deformed nuclei might have other magic numbers.

Thanks mfb.
Still 42 could be the ultimate answer to life, the universe, and everything.
'Deep thought' announced that the ultimate answer was indeed 42, but the audience would not like that.
Because they had not provided it with the ultimate question.

What are magic numbers in the nucleus?

Magic numbers in the nucleus refer to the specific numbers of protons or neutrons that are found to be more stable than others within an atomic nucleus. These numbers are believed to have special properties that make them resistant to nuclear decay.

How were magic numbers discovered?

The concept of magic numbers was first proposed by Maria Goeppert-Mayer in the 1940s. She observed patterns in the nuclear structure of atoms, specifically noting that nuclei with certain numbers of protons or neutrons were more stable than others. This led to further research and experimentation to confirm the existence of magic numbers.

What is the significance of magic numbers in nuclear physics?

Magic numbers are significant because they help to explain the stability of certain atomic nuclei. They also play a role in nuclear reactions and can help predict the properties of different isotopes. Additionally, the discovery of magic numbers has contributed to our understanding of the fundamental forces that govern the behavior of subatomic particles.

Are magic numbers considered a fact or fiction?

The existence of magic numbers is a scientific fact that has been confirmed through numerous experiments and observations. However, there is ongoing debate and research surrounding the exact mechanisms and explanations for their existence. Some theories consider them to be purely a result of mathematical patterns, while others suggest a deeper underlying physical explanation.

Can magic numbers be manipulated or controlled?

As of now, there is no known way to manipulate or control the magic numbers in a nucleus. They are believed to be inherent properties of certain atomic nuclei and cannot be artificially created or changed. However, ongoing research and advancements in nuclear physics may lead to new discoveries and potential ways to manipulate magic numbers in the future.
