2014 Neutron deficient polonium isotopes have been produced through 182W(20Ne, xn) reactions. The characteristics of disintegration of 194Po have been reviewed. Isotopes with masses 193 and 192 have been identified ; an isomeric state could be attributed to 193Po. Tome 38 N~ 20 15 OCTOBRE 1977 LE JOURNAL DE PHYSIQUE LETTRES

The distribution of alpha-radioactivity in the vicinity of uranium and of certain variant radioactive halos in biotite was investigated by the fossil alpharecoil method. Within the limits of the method I could not confirm a previously proposed hydrothermal mechanism for the origin of certain variant halo types due to polonium isotopes.

In the unconstrained MSSM, we reanalyze the constraints on the phases of supersymmetric flavour conserving couplings that follow from the electron and neutron electric dipole moments (EDM). We find that the constraints become weak if at least one exchanged superpartner mass is > O(1 TeV) or if we accept large cancellations among different contributions. However, such cancellations have no evide...

During the Second World War, Canada made several important contributions to wartime nuclear research efforts. The three main were: establishing a domestic laboratory in Montreal investigate heavy water reactor; creating supply chains provide uranium oxide, water, and polonium Manhattan Project; direct of Canadians living United States project. These efforts helped establish legacy that has pers...
