    Notes: Abstract The properties of the triplet of low-lying states in101Mo have been studied through spectroscopy of theγ radiation following thermal neutron capture in100Mo and β− decay of101Nb and through a measurement of the proton angular distributions in the100Mo(d,p) reaction with 14 MeV deuteron energy. The half-lives of the 13.5 keV state and the 57.0 keV 5/2+ state have been measured as 226(7) and 133(7)ns, respectively. These values and the quadrupole/dipole mixing ratios of the 13.5 keV and 43.5 keV transitions yield spin and parity 3/2+ for the 13.5 keV level. The E2 components in the 13.5 (3/2+ →1/2+) and 43.5 keV (5/2+→3/2+) transitions are ≦ 8·10−4 and 54(9)%, respectively. The possibility of an additional state near to the 57.0 keV level is discussed. IBFM/PTQM calculations, taking into consideration the transitional character of the100Mo boson core, account for the electromagnetic-transition and transfer-reaction pattern of the triplet of states.

    Notes: Abstract The expression of common fragile sites (c‐fra) and frequency of chromosomal aberrations were studied in peripheral lymphocytes of 50 healthy Turkish individuals (26 males and 24 females from 1 to 87 years of age) after induction with aphidicolin (APC), 5′‐fluorodeoxyuridine (FUdR), and caffeine. A correlation was seen between age and the frequency of chromosomal aberrations in APC and caffeine treated cultures, but there were no significant differences in the frequencies of chromosomal aberrations between males and females in any of the treatments. The mean frequency of aberrations induced by FUdR was significantly higher than that induced by APC and caffeine. A chromosome aberration is defined as a fragile site when present in 1% of the cells analyzed from each culture and in at least 50% of the individuals studied. Using these criteria, 12 c‐fra were observed in the three treatments: 1p21, 1q21, 2p11‐q11, 3p14, 4q31, 6q26, 7q22, 7q32, 8q24, 11q23, 16q23, and Xp22. Sites 3p14, 16q23, and Xp22 were the most frequently observed c‐fra, with only the frequency of Xp22 being significantly increased in females in APC treated cultures. The results of these studies are important as a base against which the effects of other clastogenic and environmental agents, as well as genetic background, can be compared.
