Identità in transizione. Il senso di sé personale e professionale in rapporto al cambiamento organizzativo
Il presente lavoro indaga come il cambiamento organizzativo produce delle conseguenze sul piano dell’identità professionale e personale dei lavoratori, oltre che sulla qualità della loro identificazione con l’organizzazione. Nello specifico, a 12 dipendenti di un piccolo presidio ospedaliero, colpito da un processo di ridimensionamento a causa di una rimodulazione del personale e dei posti letto, è stata somministrata un’intervista narrativa finalizzata a indagare l’impatto del cambiamento organizzativo in corso sulle identità personali e professionali. Le interviste, esplorate tramite procedure di analisi statistica del contenuto, hanno fatto emergere come i lavoratori che tendono a identi…
NEW RESULTS ON NONMESONIC WEAK DECAY OF Lambda HYPERNUCLEI WITH FINUDA
The FINUDA experiment has performed a systematic study of the NonMesonic Weak Decay (NMWD) of Λ hypernuclei analizing all the data collected from 2003 up to 2007. The results of a measurement of the spectra of protons coming from the NMWD of [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] are the subject of this paper.
Performance of HPGe detectors in high magnetic field
A new generation of high-resolution hypernuclear gamma$-spectroscopy experiments with high-purity germanium detectors (HPGe) are presently designed at the FINUDA spectrometer at DAPhiNE, the Frascati phi-factory, and at PANDA, the antiproton proton hadron spectrometer at the future FAIR facility. Both, the FINUDA and PANDA spectrometers are built around the target region covering a large solid angle. To maximise the detection efficiency the HPGe detectors have to be located near the target, and therefore they have to be operated in strong magnetic fields B ~ 1 T. The performance of HPGe detectors in such an environment has not been well investigated so far. In the present work VEGA and EURO…
Recent results on mesonic weak decay of Λ-hypernuclei
The FINUDA experiment has performed a systematic study of mesonic weak decay of p-shell Λ-hypernuclei. Recent results on the mesonic decay spectra and ratios are illustrated and discussed.

Mesonic and Non-Mesonic Weak Decay of Hypernuclei with FINUDA
Abstract The FINUDA experiment performed a systematic study of both mesonic and non-mesonic weak decay of p - shell Λ-hypernuclei. Recent results on the mesonic decay rates and the non-mesonic decay ratios are illustrated and briefly discussed.
New results on mesonic weak decay of p-shell Lambda-hypernuclei
The FINUDA experiment performed a systematic study of the charged mesonic weak decay channel of $p$-shell $\Lambda$-hypernuclei. Negatively charged pion spectra from mesonic decay were measured with magnetic analysis for the first time for ${^{7}_{\Lambda}Li}$, ${^{9}_{\Lambda}Be}$, ${^{11}_{\Lambda}B}$ and ${^{15}_{\Lambda}N}$. The shape of the $\pi^{-}$ spectra was interpreted through a comparison with pion distorted wave calculations that take into account the structure of both hypernucleus and daughter nucleus. Branching ratios $\Gamma_{\pi^{-}}/\Gamma_{tot}$ were derived from the measured spectra and converted to $\pi^{-}$ decay rates $\Gamma_{\pi^{-}}$ by means of known or extrapolate…
