dc.description.abstract For many years, Cd-110 has been considered the classic example of a vibrational nucleus within both the Collective Model and the Interacting Boson Model (IBM). As a vibrational nucleus, Cd-110 exhibits multi-phonon states. Recent studies on other cadmium isotopes have shown a breakdown of vibrational motion at the three-phonon level. The latest study on Cd-112 suggests that some of these excitations may instead result from intruder bands. The study through internal conversion electrons is important to investigate intruder structures in Cd-110, using the enhanced E0 transitions between intruder states and spherical phonon states as a signature. The nuclear structure of Cd-110 has been studied with In-110 beta decay through internal conversion electrons performed at TRIUMF using the 8pi spectrometer. The level scheme of Cd-110 through internal conversion electron transitions was constructed using the electron-gamma coincidence matrix. The sub-shell ratios and multipolarities are determined and compared with the evaluated data set. The absolute internal conversion coefficients for some mixed transitions were determined using an internal calibration efficiency for Si(Li) detector and relative efficiency for HPGe detector. The 396 keV and 708 keV E0 transitions have been observed between intruder and spherical phonon states. The E0 transition strength of 0.115(71) was determined for 708.21 keV line. en_US
