Philosophiae Doctor - PhD / The cadmium nuclei have traditionally been regarded as among the best examples
of spherical vibrational nuclei. However, advances in nuclear spectroscopy have
begun to detail the properties of these nuclei at the two and three vibrational
phonon levels, casting doubts on the vibrational assumptions. In particular, the
properties of the excited 0+n
(for n 2) levels are key to any vibrational model.
Excited 0+ states can arise in nuclei in association with the nucleon pairing degrees
of freedom, and in model spaces with collective shape degrees of freedom.
This thesis reports details of the excited 0+n
levels in the even-even nuclei 110;112Cd
and 116Sn, and the excited 9
2
+ states in 117Sb, investigated using two-proton
stripping reactions. The 108;110Pd(3He, n
)110;112Cd, 114Cd(3He, n
)116Sn and
115In(3He, n
)117Sb reactions were investigated using AFRODITE spectrometer
in conjunction with a wall of 12 plastic scintillator detectors placed 2 m away
from the target chamber.
