List of levels for 195IR

Authors: Huang Xiaolong and Kang Mengxiao | Citation: Nucl. Data Sheets 121, 395 (2014) | Cutoff date: 1-Mar-2014

Levels: For the proton-neutron interacting boson-fermion model analysis, see 1987Ci01, 1987Co08, 1986Ar03 and 1983Ci01.

Levels: For the Nilsson-model analysis, see 1987Ci01 and 1978Ya03.

Levels: For interacting boson-fermion model analysis of β decay in α=195, see 1988Na03.

Gammas: All data are from ¹⁹⁴Ir(n,γ)

Gammas: For unplaced γ’s, see ¹⁹⁴Ir(n,γ).

E(level): For the states connected by γ rays, E(level) are from Eγ and level scheme by using least-square fit to data. The others are from ¹⁹⁶Pt(pol t,α),(t,α).

J^π(level): From σ(θ) DWBA fits and analyzing power in ¹⁹⁶Pt(pol t,α), except as noted.

I(γ): Relative photon branching renormalized to 100 for the strongest γ-ray from each level.
