Lifetime measurements of the 5−1, 4−1, and 3−2 levels in 144Nd, coupled with measurements of the M1/E2 mixing of the 4−1→3−1 and 3−2→3−1 transitions, show that the transition strengths from these levels are in good agreement with th

Sources of 54 Mn, 55 Ni, and 144 Pm were placed at the center of the Gammasphere array and searches were made for the astrophysically interesting β + decay modes of these isotopes. The results of these searches are presented and the implications for

The positron decay partial half-life of {sup 56}Ni is needed to employ this isotope as a cosmic-ray chronometer. We conducted an experiment by counting a purified 2.8-{mu}Ci source of {sup 56}Ni in GAMMASPHERE in order to search for the {beta}{sup +}

The {beta} -decay half-life of {sup 54}Mn is needed to employ this isotope as a cosmic ray chronometer. We have determined the partial half-life of {sup 54}Mn for positron emission by counting a highly purified 35-{mu}Ci source of {sup 54}Mn in GAMMA

The Internal Bremsstrahlung Electron Capture spectrum from55Fe was measured with a HPGe detector. The total spectrum was unfolded taking into account the secondary detection effects and agrees with Glauber and Martin calculations. The measured intens

In order to test the possibility of using {sup 144}Pm as a clock to measure the mean cosmic-ray confinement time in the Galaxy, we counted a highly purified 1.4 {mu}Ci source of this isotope in GAMMASPHERE and searched for its astrophysically interes

We measured the electron-capture decay rate of 7Be implanted into hosts of graphite, boron nitride, tantalum, and gold. We have found that this decay rate varies by as much as 0.38% from one host to another. We also measured the electron-capture deca
