Possibility of a Spin-Isospin Density Phase in Finite Nuclei

Possibility of a Spin-Isospin Density Phase in Finite Nuclei

It is suggested that in a finite nucleus there may exist a condensed phase in which the spins of the protons are all aligned in one direction and the spins of the neutrons in the other and which has a lower energy than that of the normal phase above some density. It is found that this critical densi...

Zusammenfassung:It is suggested that in a finite nucleus there may exist a condensed phase in which the spins of the protons are all aligned in one direction and the spins of the neutrons in the other and which has a lower energy than that of the normal phase above some density. It is found that this critical density is a few times larger than the normal density and that the nucleus will have a strongly oblate shape.
