摘要: Abstract High-spin 209, 210Po isomers were recoil-implanted into tetragonal tin and the electric quadrupole coupling constants have been measured with TDPAC technique. Using a calculated value for moment of Q[ 210 Po (8 + )] = − 57 fm 2 as standard field gradient calibration, following other values are derived: 209 ( case17 −39(8) , (11 −82(19) (13 ) −62(11) . These in agreement known structure isomers. The existence more than one isomer each isotope requires data analysis procedure which takes account feeding through all levels perturbed by interaction. A two-level formalism was developed employed.
