The relationship between growth rate and buoyant density was determined for cells from exponential-phase cultures of Escherichia coli B/r NC32 by equilibrium centrifugation in Percoll gradients at growth rates ranging from 0.15 to 2.3 doublings per h

Cell buoyant densities were determined in exponentially growing cultures of Escherichia coli B/r NC32 and E. coli K-12 PAT84 by equilibrium centrifugation in Percoll gradients. Distributions within density bands were measured as viable cells or total

— Seven axenic wild-type and repair-deficient mutant strains of the cellular slime mold Dictyostelium discoideum have been treated with the furocoumarin 8-methoxypsoralen (8-MOP) up to 50 μg/mζ and then exposed to near ultraviolet light (UVA 320-

Energy levels of 151 Eu and 153 Eu were populated by Coulomb excitation with 12 MeV alpha particles. Alpha particles scattered at 110° and 145° were analysed in a magnetic spectrograph. Levels were located in 151 Eu at these energies: 195, 313, 511

Energy levels of 139 La were populated by Coulomb excitation with 12 MeV α-particles. Alpha particles scattered at 100°, 120° and 160° from thin 139 La 2 O 3 targets were analyzed in a magnetic spectrograph. In a complementary experiment with thi

Cross sections for the reaction 87 Rb(d, p) 88 Rb induced by 4 to 6 MeV deuterons were measured to obtain spectroscopic data on levels in 88 Rb. The Q -value for the reaction to the ground state of 88 Rb was 3.837 ± 0.020 MeV. In addition twenty-thr

Spectra of prompt internal conversion electrons with energies up to 2 MeV were obtained from targets of 159Tb, 165Ho, 169Tm, 175Lu and 181Ta bombarded with 12 MeV protons. Gamma-electron coincidence spectra were also measured. Most of the observed li
