NUCLEAR REACTIONS ⁹Be(¹²⁴Xe, X)⁸⁸Zr/⁹⁰Nb/⁹⁰Mo/⁹⁰Rh/⁹¹Nb/⁹²Mo/⁹²Rh/⁹²Tc/⁹²Ru/⁹³Ru/⁹⁴Ru/⁹⁴Pd/⁹⁴Ag/⁹⁵Pd/⁹⁵Ag/⁹⁶Pd/⁹⁶Ag/⁹⁷Cd/⁹⁸Cd/⁹⁸In/⁹⁸Ag/¹⁰⁰Sn, E=345 MeV/nucleon; measured reaction products, half-lives of micro-second isomers and isomeric ratios using BigRIPS, ZeroDegree spectrometer, WAS3ABi and EURICA array at RIBF-RIKEN facility. Comparison of isomeric ratios with abrasion-ablation model combined with sharp cutoff model.

RADIOACTIVITY ^88mZr, ^90mNb, ^90m,92mMo, ^92mRh, ^92mTc, ^92m,93mRu, ^94m,96mPd, ^96m,98mAg, ^98mCd(IT)[from ⁹Be(¹²⁴Xe, X), E=345 MeV/nucleon]; measured Eγ, Iγ, branching ratios, γγ-coin, isomer half-lives by γ(t), isomeric ratios using BigRIPS, ZeroDegree spectrometer, WAS3ABi and EURICA array at RIBF-RIKEN facility. ⁸⁸Zr, ⁹⁰Nb, ^90,92Mo, ⁹²Rh, ⁹²Tc, ^92,93Ru, ^94,96Pd, ^96,98Ag, ⁹⁸Cd; deduced levels, J, π, multipolarities, B(E1), B(E2), B(M2), B(E3), B(E4). Comparison with previous experimental results, and with shell model calculations using NUSHELLX code and SLGM interaction. ¹⁰⁰Sn; search for a core-excited isomer in ¹⁰⁰Sn decaying by E2 proved negative; calculated upper limit for half-life and lower limit for Eγ of an hypothetical isomer in ¹⁰⁰Sn decaying by E2.
