Positive parity states and some electromagnetic transition properties of even-odd europium isotopes

The positive-parity low-spin states of even-odd Europium isotopes (^151–155Eu) were studied within the framework of the interacting boson-fermion model. The calculated positive low-spin state energy spectra of the odd Eu isotope were found to agree quite well with the experimental data. The B(E2) values were also calculated and it was found that the calculated positive-parity low-spin state energy spectra of the odd-A Eu isotopes agree quite well with the experimental data.
