The electromagnetic mean squared radii, 〈r2〉E and 〈r 2〉M, of Λ(1405) are calculated in the chiral unitary model. We describe the excited baryons as dynamically generated resonances in the octet meson and octet baryon scattering. We evaluate values of 〈r2〉E and 〈r 2〉M for the Λ(1405) on the resonance pole and obtain their complex values. We also consider Λ(1405) obtained by neglecting decay chan...
The evaluation of the 99Tc half-life is described in the next section. Table 2 summarizes the measurements and their methodology. Although the β-decay of 99Tc is practically 100 % from its 9/2+ ground state to the 5/2+ ground state of 99Ru, 1973LE10 and 1974EN02 observed a β-decay with a very small intensity to the 3/2+ first excited state of 99Ru. Thus, its energy, half-life and the multipolar...
The ground and first excited states in 15F were studied in resonant elastic scattering using the thick sCH4d gas target method in inverse kinematics with a separated 14O beam. An analysis of the excitation functions of the elastic scattering was carried out with the potential model. The quantum numbers 1/2+ (ground state) and 5/2+ (first excited state) were assigned to the lowest two states in ...
The photoinduced excited-state processes in 1,1'-diethyl-2,2'-cyanine iodine are investigated using femtosecond time-resolved pump-probe spectroscopy. Using a broad range of probe wavelengths, the relaxation of the initially prepared excited-state wavepacket can be followed down to the sink region. The data directly visualize the directed downhill motion along the torsional reaction coordinate ...
