“…Line shapes and sidefeeding Line-shape fitting has now also been applied to the Sm data described in [8], and slightly slower sidefeeding times are indicated by the analysis [35]. The lineshape analysis for ' Nd [7] indicated much slower feeding timesaround a factor of four slower than the inband times. A similar result has recently been found for Gd [9].…”

“…In the determination of Qo for ' Nd reported in [7], both a centroid shift and a full line-shape analysis were carried out. The line-shape analysis indicated that the centroid shift analysis was unreliable due to the sidefeeding times being much slower.…”

“…The set of codes used in the ' Nd analysis [7], originally developed by [21] but now modified, were employed here. An array of velocity profiles (theoretical line shapes) were generated by projecting a set of 5000 Monte Carlo histories (simulated collision paths) in -1.2 fs time steps towards the specified detector configurations at 37' and 143'.…”

“…Hence there is a greater sensitivity to background subtraction and, as noted in [7], contaminant lines. One way to check the line-shape fitting (and hence the reliability of the centroid shift method) is to use another technique to measure the Qo of these bands.…”

Lifetimes of the decay from superdeformed to normal deformed inNd135

“…In a previous experiment [4] For comparison, the transition probabilities of several transitions in the normally deformed ground band were also determined.…”
