A double semigroup is a set equipped with two associative binary operations satisfying the middle-four interchange law. A double inverse semigroup is a double semigroup in which both operations are inverse semigroup operations. It is shown by Kock (2007) that all double inverse semigroups must be commutative. In this thesis, we define the notion of a double inductive groupoid which admits both a construction of double inverse semigroups given any double inductive groupoid, and vice-versa. These constructions are functorial and induce an isomorphism of categories between the category of double inductive groupoids with inductive functors and double inverse semigroups with double semigroup homomorphisms. By a further investigation of double inverse semigroups, we are able to show that the two operations of any double inverse semigroups must coincide and thus double inverse semigroups are commutative inverse semigroups.

In light of present (EXO) and future (BOREXINO & XMASS) projects searching for evidence of the, as yet, unobserved double-beta decay of 136Xe, an atomic mass difference of 136Xe – 136Ba was determined using the high-precision Manitoba II mass spectrometer at the University of Manitoba. The Q-value for this difference was determined to be 2458.72(56) keV. The double-beta decay mode can be either neutrino (ββ2υ) or neutrinoless (ββ0υ), where the latter would be proof of the Majorana nature of neutrinos. A ββ0υ decay, which violates several principles of the Standard Model of particle physics, would emit only electrons and would provide a defined peak at the Q-value for the decay. This decay would also require the Majorana neutrino to have a non-zero rest mass and be its own antiparticle. Results of mass measurements on mass doublets of 135Ba, 136Ba, 137Ba, and 138Ba will be given. An improved measurement of the 116Cd35Cl - 114Cd37Cl doublet, previously done by Meredith et al. in 1973, will also be given.
