Quasi-fission reactions as a probe of nuclear viscosity

Fission fragment mass and angular distributions were measured from the ^{64}Ni+^{197}Au reaction at 418 MeV and 383 MeV incident energy. A detailed data analysis was performed, using the one-body dissipation theory implemented in the code HICOL. The effect of the window and the wall friction on the experimental observables was investigated. Friction stronger than one-body was also considered. The mass and angular distributions were consistent with one-body dissipation. An evaporation code DIFHEAT coupled to HICOL was developed in order to predict reaction time scales required to describe available data on pre-scission neutron multiplicities. The multiplicity data were again consistent with one-body dissipation. The cross-sections for touch, capture and quasi-fission were also obtained.Comment: 25 pages REVTeX, 3 tables, 13 figures, submitted to Phys. Rev

Autonomy in long-term care: a need, a right or a luxury?

Doyal and Gough’s theory of human need highlighted that personal autonomy is a universal need and human right, essential for well‐being. In applying their theory to older disabled people in the UK the author suggests that their ‘minimally autonomous’ threshold would exclude some older people in long‐term care who still have a fundamental need for autonomy or, alternatively, extant autonomy. The disability movement has highlighted that independent living is fundamental to achieving self‐determination for disabled people and debate on equality and caregiving emphasises the autonomy of carers. However, there is a lack of recognition in both academic research and government policy of autonomy as a need and right of older disabled people. The author argues that autonomy is a human right of older people living in long‐term care settings, but that social rights are necessary to facilitate their autonomy
