Energy Levels of Light Nuclei. IV

XXXVIII.The anomalous spin of47Ti

“…This arises from the supposition that the allowed fi-transition is to the ½-~-ground state of 19F, implying that 190 is 1 oU-~ or 3/2-~, but not 5/2-~. It does not seem eei~ain, however, that the fl-deeay does not lead to the two very low excited states of ~gF at 0.11 and 0.19 Mev quoted by Ajzenberg and Lauritsen (1952). Until this point is settled the possibility of 5/2-~ remains ; but even if the transition is to the ground state of 19F, it is still possible that 190 has a ½÷ ground state.…”

New alpha-decay barrier penetrabilities with Igo potential: Even- and odd-mass nuclei

“…The exact value for Ma, Mr 4,00278 a. na. u. is from AJZE~BERC and LAUlUTSE~'S [5] measurement on the mass of the He atom, for Mr JELEPOV and PEKER'S data [6] are used.…”

Reactor Shielding Design Manual

“…The reason for this can be seen from Eq. 28 and the paragraph following. The average (a)r, (q)[, and (a), are found by expressing each a s a simple exponential and averaging over the region thickness.…”
