List of levels for 102MO

Author: D. De Frenne | Citation: Nucl. Data Sheets 110, 1745 (2009) | Cutoff date: 31-Dec-2008

E(level): The level energies were calculated using a least-squares procedure using the Adopted Gammas.

J^π(level): Unless noted otherwise, from observed band structure and systematics in ²³⁸U(α,Fγ) and ¹⁶⁸Er(³⁰Si,xγ)

J^π(level): After contact with S.Lalkowski,( November 14, 2007), one of authors of the ¹⁶⁸Er(³⁰Si,Xγ) experiment (2007La03), the evaluator got convincing evidence for the correctness of the level scheme and Jπ assignments for members of band(β) presented by (2007La03) over these of (2004Hu02) in ²³⁸U(α,Fγ). The interpretation of the observed band structure given by (2007La03)is a.o. based on systematics of very reliable data on ^98,100Mo and ¹⁰⁴Ru. Nevertheless an experimental confirmation of the results of 2007La03 would be very welcome.

T_1/2(level): Unless noted otherwise, determined by the recoil-distance Doppler-shift method (1975Bo39) from ¹⁰⁰Mo(¹⁸O,¹⁶Oγ), except for g.s. and 296 level

E(γ): The gamma energies were calculated using as a weighted average using gammas of ¹⁰²Nb {β|+ decay (1.3 s),¹⁰²Nb {β|+ decay (4.3 s), ¹⁰⁰Mo(¹⁸O,¹⁶O), ²⁴⁸Cm,²⁵²Cf SF decay, ¹⁰⁰Mo(t,pγ), ²³⁸U(α,Fγ) and ¹⁶⁸Er(³⁰Si,xγ)

I(γ): Relative branchings of each level were deduced as a weighted average of data from ¹⁰²Nb β^- decay (4.3 s), ¹⁰⁰Mo(t,pγγ),¹⁶⁸Er(³⁰Si,Xγ) and ¹⁰⁰Mo(¹⁸O,¹⁶O)

M(γ): Unless noted otherwise, deduced from level scheme
