List of levels for 80RB

Author: Balraj Singh | Citation: Nucl. Data Sheets 105, 223 (2005) | Cutoff date: 22-Jun-2005

Other reaction:

1979Wo03: ⁴⁰Ca(⁴⁰Ar,π) E=1.05 GeV/nucleon.

Mass measurement: 1998Is06, 1994Ot01, 1982Au01, 1979Al19

Nuclear structure calculations: 2004Sh18

Q-value: Note: Current evaluation has used the following Q record $ -1865 10 9441 9 5019 8 -4309 12 2003Au03

E(level): From least-squares fit to Eγ’s.

J^π(level): For high-spin (J>3) states, the assignments are from in-beam γ-ray studies (2003We13,2000Ca07,1998Ta07,1992Do10), based on angular correlation data and band associations. The parentheses in some cases are added by the evaluator since results of γγ(θ) are not quoted by above authors and in general strong arguments for Jπ assignments are lacking

T_1/2(level): Half-lives in the nanosecond region are from 1992Do10 in γγ(t) study using ⁶⁸Zn(¹⁹F,α3nγ) reaction; those in the picosecond region are from 2000Ca07 using Doppler-shift attenuation method in ⁵⁵Mn(²⁸Si,2pnγ) study
