FIG. 1. (Color online)Identification matrix showing the en- en-ergy loss in the ionization chamber of VAMOS as a function of the mass-over-charge ratio determined from the time of flight and magnetic rigidity of the spectrometer
FIG. 2. Gamma-ray spectra obtained for the distances x = 40, 350 and 750 µm. The low (high) energy peak corresponds to the fast (slow)component of the 3/2 − 1 → 7/2 −1 transition in 63 Co.
FIG. 4. (Color online) Left: Total kinetic energy as a function of the scattering angle in the laboratory frame
FIG. 5. (Color online) Left panels: Systematics of the B(E2) values (a) and the experimental energies (b) in the even-N Fe, Co and Ni isotopes

In the impact parameter di erence method the knowledge of the tau pair production point is limited by the size of the interaction region, whose dimensions are larger than the

When a tau decayed into final states with only one charged particle (one-prong decays), the lifetime information was contained in the impact parameter of that particle with respect

La phase de post-compréhension et de réflexion de notre synthèse ou unité concrète, affirmait que nous avions conclu que c’était le croisement entre le style dominant et la

We have seen that computer simulation of multiexponential decay curves which model the ex- citation and detection conditions is a convenient means of studying the

distribution of the y-rays emitted by the stopped nuclei, by using a thick F2Ba target to stop the recoil-. ing

We tackle the problem of observer design for linear and nonlinear systems despite the presence of a time-varying pointwise delay in the output measurements.. The fact our

The first instrument (called LEDIF) employs a novel flowcell, 6 UV LEDs as excitation sources, a wideband lamp, and a spectrometer to measure steady state chemical

Here BIP is relative deviation from the sta- tionary value of the metastable atom con- centration; J is the value proportional to the constant component of the discharge
