Book excerpt: The nuclear radiations of nuclides: U233, Pu239, Bk243, Bk244, Bk245, Bk246, Bk249, Cf249, and Fm255 were investigated with high-resolution spectrometers. The [alpha]-particle spectra of all nuclides except Bk249 were measured with 6 mm diameter surface-barrier detectors. Bk249 [alpha]-particles were analyzed with a double-focusing magnetic spectrograph. The [gamma]-singles were examined with the recently developed Ge(Li) and Si(Li) detectors coupled with very-low noise 'internal FET' preamplifiers. Weak alpha groups were observed in coincidence with [gamma]-rays, detected with a NaI(Tl) scintillation spectrometer. To improve the over-all coincidence efficiency a new coincidence apparatus was designed and built. This instrument consisted of a cooled 4.5 cm diameter semiconductor detector for [alpha]-particle detection and a 3 cm diameter by 2.7 cm long Ge(Li) detector for [gamma]-ray analysis. The Ge(Li) detector could also be replaced with a NaI(Tl) detector. Cf249 conversion electrons were measured with a cooled Si(Li) detector coupled with an internal FET preamplifier. On the basis of the present work and previous information, energy-level diagrams of the daughter nuclei have been constructed. The levels have been grouped into rotational bands built on Nilsson single-particle states. Because of identification of several rotational members of the bands, definite Nilsson quantum number assignments have been made in most cases. The alpha intensity calculations of Poggenburg were found quite helpful in making these assignments. A strong Coriolis effect was observed in the Am245 levels populated by the alpha groups of Bk249. Calculations were made with Nilsson wave-functions, and these were found to agree with the experimental results. The Coriolis interaction was found important in almost all cases; the effect was very noticeable in the level spacings between the rotational members of the bands. High-lying bands in Cm245 (at 644 keV) and cf251 (at 550 keV) were observed and 4 rotational members of each were identified. The modes of de-excitation of these levels indicate very small or no vibrational characters in them. This suggests that the vibrational bands, in this region lie at very high energies (≈1 MeV) above the ground state.

Available in PDF, EPUB and Kindle. Book excerpt: This advanced textbook presents an extensive and diverse study of low-energy nuclear physics considering the nucleus as a quantum system of strongly interacting constituents. The contents guide students from the basic facts and ideas to more modern topics including important developments over the last 20 years, resulting in a comprehensive collection of major modern-day nuclear models otherwise unavailable in the current literature. The book emphasizes the common features of the nucleus and other many-body mesoscopic systems currently in the center of interest in physics. The authors have also included full problem sets that can be selected by lecturers and adjusted to specific interests for more advanced students, with many chapters containing links to freely available computer code. As a result, readers are equipped for scientific work in mesoscopic physics.
