We model the odd-neutron nucleus 233U as a 2Β°8pb+24Ne+n system. The odd neutron occupies lg9/2, 0in/2, 0jls/z, 2ds/2, 3sl/2, lg7/2 and 2d3/2 states with energies taken from the known 209 24 + + + spectrum of Pb, while the Ne cluster occupies 0 , 2 , 4 .... and 1-, 3-, 5-..., states whose energies ar

The Ξ³-rays following the Ξ² -decay of 229 Ac have been investigated by means of Ξ³-ray singles and Ξ³Ξ³-coincidence measurements using Ge detectors. Multipolarities of 40 transitions in 229 Th have been established by measuring conversion electrons with a mini-orange electron spectrometer. The half-live
## Abstract The thermodynamics of the __q__βstate Potts model is calculated by the cluster approximation. With two, three, and four particles as the basic cluster the free energy is obtained for any __q__. It is found that the transition is of the first order for all twoβdimensional and threeβdimen
Detailed angular distributions for the 230,232 Th(d, t) 229,231 Th reactions were measured with 17 MeV deuterons, using a magnetic spectrograph to analyze the reaction products. Comparisons with distorted wave Born approximation predictions were used to determine -values and spectroscopic strengths
