S-wave approximation for asymmetry in nonmesonic decay of finite hypernuclei
(2007-11-28)
We establish the bridge between the commonly used Nabetani-Ogaito-Sato- Kishimoto (NOSK) formula for the asymmetry parameter aΛ in the Λ→p→np emission of polarized hypernuclei, and the shell-model (SM) formalism for finite ...
Nonmesonic weak decay of Λ-hypernuclei within independent-particle shell-model
(2010-08-27)
After a short introduction to the nonmesonic weak decay (NMWD) ΛN→nN of Λ-hypernuclei we discuss the long-standing puzzle on the ratio Γn/Γp, and some recent experimental evidences that signalized towards its final solution. ...
Microscopic model to nucleon spectra in hypernuclear non-mesonic weak decay
(Elsevier Science, 2013-01-08)
A consistent microscopic model is applied to the calculation of the nucleon emission spectra in the nonmesonic weak decay of Λ-hypernuclei. We adopt a nuclear matter formalism extended to finite nuclei via the local density ...
Kinetic energy sum spectra in nonmesonic weak decay of hypernuclei
(2008-10-16)
We evaluate the coincidence spectra in the nonmesonic weak decay (NMWD) ΛN→nN of Λ hypernuclei Λ4He, Λ5He, Λ12C, Λ16O, and Λ28Si, as a function of the sum of kinetic energies EnN=En+EN for N=n,p. The strangeness-changing ...
