“…The mean life (7) of the state together with the measured attenuation factors ( F ) determine points on F ( z ) curves for two different ion recoil velocities. These points are shown in figure 7 plotted together with F(z) curves calculated from the Blaugrund (1966) method and a Monte-Carlo (Hanson and Puhach 1972) approach using, in both cases, the slowing down theory of Lindhard et al (1963). The data are consistent with both methods of calculation.…”

Two states in 59Cu populated by the reaction 58Ni(p,y) at proton energies of 3547 and 1833 keV have been studied. An investigation of the gamma ray transition between the resonance states and the gamma ray decay of the lower energy resonance has yielded rP/r = 046 k 0.04 and (2J + 1) ryrp/r = 0,046 f 0.005 eV for the lower resonance. The spin of the lower resonance (E, = 5219 keV) has been deduced to be 3 and therefore the total width of the state is 0,038 0.009 eV, corresponding to a lifetime T = 17.5 k 4.1 fs. The Doppler shift attenuation method used to determine the lifetime of this state yields the values 13.5 2 fs. It is concluded that, within experimental error, there is agreement between observation and standard ion energy loss theory for the case of Cu recoiling in Ni. 2 fs and 16 NUCLEAR REACTIONS 58Ni(p, Y )~~C U , E, = 1833 and 3547 keV resonances; measured a(E, E,, e), Doppler shift attenuation. 59Cu; deduced levels, J , resonance parameters, T.
