Structure of low-lying states of 76,78,80,82Se deduced from (p, p′) scattering at 16 MeV

摘要: Abstract Angular distributions of dσ dΩ and A y have been obtained for elastic inelastic scattering 16 MeV protons leading to the first two 2 + states lowest excited 0 , 4 3 − levels 76,78,80,82 Se. Results analyzed in coupled-channels framework assuming vibrational model, rotation-vibration asymmetric rotational model (ARM) its extension β-vibrational states. There is no one which can describe simultaneously all data. However, we find from our ARM-based analysis, provides best overall description even-parity states, evidence different deformations second Also observe that nuclear structure 82 Se seems be quite lighter isotopes studied. We find, too, 76,78,80 do not behave as simple octupole Nuclear extracted present measurements compared with those earlier (n, n') Coulomb excitation measurements. Finally, need complex and/or deformed spin-orbit potentials discussed.
