J. Hans D. Jensen (physicist)

J. Hans D. Jensen was a German physicist known for his groundbreaking work in nuclear physics. He co-developed the nuclear shell model, which explains how protons and neutrons are organized inside an atomic nucleus, similar to electrons in an atom. This model helps scientists understand the stability and structure of different elements. Jensen's contributions significantly advanced the understanding of nuclear behavior, influencing both theoretical physics and practical applications like nuclear energy. His work, alongside others, earned him the Nobel Prize in Physics in 1963.
