    Notes: Abstract A Residue Implantation Detection System has been used in conjunction with the Daresbury Recoil Mass Separator in a search for radioactivity from the unknown nuclides108I and105Te. In the reaction of 260 MeV58Ni ions with a54Fe target two new decay lines at energies of 3.730±0.025 MeV and 3.885±0.025 MeV corresponding to cross sections of approximately 0.3 μb and 0.4 μb respectively were identified in theA=108 region of the separator's focal plane. These decay lines are tentatively assigned to the alpha decays of108I. No evidence for a proton decay branch of this nuclide could be found. In a second reaction in which a50Cr target was bombarded with 230 MeV58Ni ions, no alpha decay peak from105Te could be identified. Cross section dependent half life limits were determined from which correspondingQ-value limits were deduced.

    The time dependence of surface energy in cohesive fracture (1970)

    Notes: The time-temperature dependence of the cohesive fracture energy is deduced from experiments on a centrally cracked sheet of butadiene-acrylonitrile-acrylic acid viscoelastic terpolymer crosslinked with an epoxy curing agent. Analytic results based upon a cylindrical flaw model of the crack permit the segregation of the fracture energy time dependence from that of the relaxation modulus.
