Lifetimes of Excited States of Nuclei in the Mass Range 28<A<56 by Delayed CoincidenceBoulter, James Frederick 05 1900 (has links)
<p> A study of the inter-multiplet Ml transition probability for states populated by the (n,γ) reaction in a number of odd-odd nuclei has been performed. Using a high resolution delayed coincidence system and specially developed calibration and data analysis techniques, lifetime measurements have been made for low energy transitions in 28Al, 32P, 40K, 46Sc, 52v and 56Mn. A theoretical model which uses the static magnetic dipole moments of the corresponding odd-A nuclei as the base states has been investigated and was shown able to produce a very satisfactory agreement with the experimental inter-multiplet B(Ml) values.</p> / Thesis / Doctor of Philosophy (PhD)

Thermal Neutron Capture Studies of Some Light Odd-Odd NucleiIshaq, Abul Faiz Mohammed 09 1900 (has links)
<p> Thermal neutron capture studies have been made of the odd-odd nuclei, 20F, 24Na, 28Al, 32P, 36Cl and 40K. The gamma ray spectra have been studied using a Ge(Li) pair spectrometer and revised decay schemes are presented for these nuclei. The Q-values and gamma ray multiplicities have been obtained for the reactions studied. The average partial widths for primary Ml and El transitions have been calculated for the six nuclei and compared with the theoretical estimates. The features of the capture gamma ray spectra are discussed and it is observed that for the six nuclei studied, the total intensity in the spectrum above the energy of 0.3 times the Q-value is nearly the same (~1.4 photons/capture).</p> / Thesis / Doctor of Philosophy (PhD)
