The decay of 93Kr was observed to have 217 γ rays, 203 of which are placed in a level scheme for 93Rb comprising 56 excited levels. Over 98% of the observed γ-ray intensity is contained in each of the level schemes. Spin and parity assignments are proposed, whenever possible, on ...

If mJ = 2mc is taken, the decay rates depend on 1 . m8 c (6) However, the value mc = 1.25 ± 0.09GeV[6] shows that mJ = 2mc is not a good approximation. Because of the cancellation between mJ and mc in the factor of Eqs.(3,4) {2m2 ? 3m2′ (1 + J η 2mc m3 ) ...
2\\gamma-decays of scalar mesons (\\sigma(600), f_0(980) and a_0(980)) in the Nambu-Jona-Lasinio model The two-photon decay widths of scalar mesons \\sigma(600), f_0(980) and a_0(980) are calculated in framework of the local Nambu-Jona-Lasinio model. The con... MK Volk...

作者: A Ferroglia 摘要: We briefly review the current status of the calculation of the next-to-next-to-leading-order (NNLO) QCD corrections to the branching ratio of the (B) over bar -> X-s gamma decay, and we also present the recent theoretical estimate of the latter quantity [1]....
a –.41 delta but only .02 gamma. Rolling maintains roughly the same delta exposure but cuts gamma in half. Yes, some positive theta is sacrificed because the 259-strike put with 53 days has more theta, but it will decay at a slower rate than the 259-strike put with 18 days. But ...
Theradionuclideinjected into the patient should preferably decay by the emission of a single γ, and the lower theEγthe better becomes the resolution of the image. Since the detectors are energy sensitive, the camera can be tuned to the primary unperturbed (Ch. 6) γ's, i.e. the signals...
New high spin states in $^{25}mathrm{Mg}$ (up to 13.3 MeV in excitation) have been located using the $^{12}mathrm{N}$,p$gamma${}${)}^{25}$Mg reaction at a laboratory beam energy of 23.5 MeV. Gamma decay from 28 neutron unbound levels has been observed (24 of which are repor...
