List of levels for 72GA

Authors: D. Abriola, A.A. Sonzogni | Citation: Nucl. Data Sheets 111,1 (2010) | Cutoff date: 1-May-2009

Gammas: Primary γ’s from ⁷¹Ga(n,γ) are given under ⁷¹Ga(n,γ) only.

Q-value: Note: Current evaluation has used the following Q record 3997.5 106520.48 198548 3 -5446.1 18 2009AuZZ

E(level): Except as noted, levels below 2 MeV with ΔE=3 are from ⁷¹Ga(d,p); energies of other levels are deduced from adopted γ-ray energies, mainly from ⁷¹Ga(n,γ). The (d,p) levels are systematically 2 keV higher than the (n,γ) energies

T_1/2(level): From βγ and γγ delayed coincidence in ⁷²Zn β^- decay, except where noted.

E(γ): Mainly from ⁷¹Ga(n,γ). For levels below 210, γ’s from ⁷²Zn β^- decay have been used to obtain average values.

I(γ): Relative branchings are given, mainly from ⁷¹Ga(n,γ).

M(γ): From α(K)exp, see ⁷²Zn β^- decay.
