Sun Yang's group from Shanghai Jiaotong University predicts a new mode of collective motion of atomic nuclei

Recently, the research group of Professor Sun Yang from the School of Physics and Astronomy, Shanghai Jiao Tong University, in cooperation with colleagues from Lanzhou University and the University of Tennessee, predicted a new type of collective motion pattern of atomic nucl.

Strongly correlated quantum many-body problem is one of the most active research directions in modern physi.

An atomic nucleus is a microscopic system composed of protons and neutrons from as small as a few to as large as more than two hundr.

In nuclear physics, isospins describe protons and neutrons as two states of one particle (nucleo.

However, since the 1+ state of scissors vibration was first verified in 1984, the complete scissor vibration-rotation band (ie, 2+, 3+.

After systematic calculations, they believe they have found a general feature of the 1+ scissor-rotating band of nucl.

The research group of Professor Sun Yang thanked the National Natural Science Foundation of China for the support of the key project of the Joint Fund of the National Natural Science Foundation of Chi.
