Investigation of the low laying energy levels structure of the rich neutron isotopes 78-88 Kr

Abstract EN

The low lying levels structure and electric quadrupole transitions of the rich neutron 78-88 Kr nuclei have been studied by using the Interacting Boson Model-1 (IBM-1).

The calculated results are in good agreement with recent experimental data.

The results obtained and the values of parameters used in this calculations indicated that Kr isotopes have a vibrational with small amount of O (6) properties appears to be constant with increases of Atomic number of isotopes.

In actual study many of energy level were ensure like (62+) in 80Kr, (23+), (42+) and (61+) in 82Kr, 3+ in 84Kr and 3+ in 88Kr.
