ScholarBank@NUS Repository. https://doi.org/10.1007/BF01295458 | Abstract: | To date, ten experimental measurements of the asymmetry parameter have been made for the positron decay of52Mn. The Fermi to Gamow-Teller mixing ratio y can be deduced from such measurements and this quantity is important because the time-reversal violating amplitude is proportional to y/(1+y2). Our theoretical calculation using the Collective Model yields y=- 3.5×10-4 for the deformation parameter β=0.1 and y=- 4.6×10-4 for β=0.2. Such small values of y are consistent with time-reversal invarisance. © 1989 Springer-Verlag. | Source Title: | Zeitschrift für Physik A Atomic Nuclei | URI: | http://scholarbank.nus.edu.sg/handle/10635/98268 | ISSN: | 09301151 | DOI: | 10.1007/BF01295458 |
