Chapter I describes several nuclear models which have had some success in describing the known properties of nuclei in the 2s-ld shell. Brief reviews of attempts to describe ²⁷A1 and ³²S in terms of nuclear models are given in chapters 3 and 4. The principles and theory behind the Doppler shift attenuation method (DSAM) and gamma-ray angular distribution and polarisation experiments are outlined in chapter 2,together with a brief description of the 61 cm double focussing magnetic spectrometer.1 venNuclear spectroscopyNuclear shell theory197310.25911/5d70efc93cbda2017-11-22
