Relative even and odd parity levels within the nuclei in the iron region

چکیده مقاله

In the current study, the ratio of the nuclear level densities with odd and even parities for (58)Fe were calculated and compared with those of (60)Ni, using a microscopic-macroscopic computational method. It was shown that the level densities of odd and even parities for even-even nuclei are not equal at low energies. However, increasing excitation energy reduces the difference between odd and even parities and equality is gained gradually.
